The 12 Best Sci-Fi TV Shows Of All Time, Ranked

by

As a devoted enthusiast, I’d say that science fiction is a genre where authors explore the realm of speculative ideas, encompassing sub-genres such as horror, fantasy, and more. This narrative form often delves into the imaginative use of science and technology, even if it strays from what we currently know about the universe’s fundamental rules and scientific facts. It’s usually centered around themes like space exploration, time travel, artificial intelligence, futuristic weaponry, extraterrestrial life, or any other tech-driven concept. What truly sets science fiction apart is its focus on depicting the dynamic between humans and technology.

In this compilation, we’ve gathered science fiction series that delve into the concept of coexisting with advanced technology, portraying worlds where technology and science have surpassed present-day limits. These stories offer a backdrop for human narratives set in these futuristic landscapes. Ranging from lighthearted and entertaining to thought-provoking and visionary, both books and TV shows are included. We aimed to select series that encompass a range of tones and themes, giving special attention to those with dedicated fanbases. Additionally, we took cultural significance and critical acclaim into account, but in the realm of science fiction, the level of devotion from fans is often a reliable gauge of quality and enduring appeal, which served as our primary consideration.

12. Dark

The atypical German series “Dark” on Netflix demonstrates that science fiction can surpass cultural and linguistic barriers. Even though it necessitates the use of subtitles for those unfamiliar with German, “Dark” is both heartfelt and captivating. It provides a distinct perspective on time travel without compromising on character development or intense tension. Its emotional resonance is conveyed through an impactful soundtrack and striking visuals. In essence, “Dark” is one of the finest science fiction series available on Netflix, offering a subtle brilliance.

Dark” concludes with a mix of fulfillment and sadness. Throughout its episodes, it maintains a thoughtful and introspective atmosphere. Unlike many standard science fiction tales, this series often feels more like a fable or supernatural story. However, there’s always an intellectual depth running beneath the surface. The narrative revolves around scientific concepts, primarily focusing on using science to alleviate the unbearable sorrow brought about by losing loved ones. Science fiction’s purpose is to delve into profound philosophical questions while keeping them theoretically safe, and “Dark” effectively achieves this goal.

11. Black Mirror

Many enthusiasts of classic television might argue that “The Twilight Zone” is the epitome of excellence for sci-fi and fantasy anthology series. However, some may counter that “The Outer Limits,” which debuted in 1963, is a superior representation of the genre due to its dedicated exploration of science fiction narratives. Among contemporary anthology shows, it’s likely that “Black Mirror” stands out as the most successful, having originated in the UK before being acquired by Netflix in 2015. With seven seasons under its belt, this show is unique because you can watch episodes without worrying about the sequence, thanks to its anthology structure.

One effective aspect of “Black Mirror” is its timing – it debuted in 2013 when the influence of the internet on society had become so intricate and profound that it was challenging to articulate its full impact. By this point, many people were beginning to understand that technological progress often brings as many problems as solutions, a realization that continues today. “Black Mirror” tackles themes such as excessive social media use (“Nosedive,” Season 3, Episode 1), the intersection of virtual reality and mortality (“San Junipero,” Season 3, Episode 4), and even cancel culture (“Hated in the Nation” Season 3, Episode 6), all set in a future that’s just a stone’s throw from our own.

10. Loki

Due to the relentless effort put forth by Marvel Studios, superhero films and series have carved a unique niche for themselves within the realms of science fiction and fantasy genres. However, these elements haven’t diminished the presence of sci-fi and fantasy aspects in most superhero narratives. In fact, recent shows like “Loki” have further emphasized their sci-fi characteristics. Among the Marvel Cinematic Universe (MCU) productions, “Loki” has been particularly noteworthy since “Avengers: Endgame,” not only because of Tom Hiddleston’s captivating portrayal of Loki but also due to its exceptional quality overall.

The series “Loki” presents viewers with the Time Variance Authority (TVA), an entity operating beyond the confines of space and time, tasked with maintaining the sanctity of the timeline. Loki, who is not always a trustworthy hero, having deceived Thor and numerous other supposed allies on multiple occasions, and possessing the power to create illusions resulting in self-cloning, displays an insatiable curiosity that audiences can easily empathize with. In his quest for understanding the TVA’s secrets, Loki discovers a sense of purpose and vitality he has never known before. Although it remains uncertain if “Loki” will return for a third season, its first two seasons form a self-contained narrative and introduce numerous intriguing sci-fi elements to the Marvel Cinematic Universe (MCU).

9. Silo

Apple TV+ boasts some of the most groundbreaking and unique content among current streaming services, yet it remains relatively unknown due to Apple’s reputation for underpromotion of their products. Notably, the service has garnered acclaim for its science fiction series such as “Severance,” “Foundation,” and “Silo.” Interestingly, “Silo” made a strategic move by altering its name prior to the premiere, which proved beneficial, and the quality only improves from there.

The intricacies of “Silo,” from its deep-seated mysteries to its carefully chosen props and color filters, are all deliberate. The series boasts Rebecca Ferguson as the intelligent, composed lead character, Juliette. While the conventional sci-fi aspects – the design of the silo-dominated dystopia, human interaction with technology crucial for survival – exhibit sophistication, what truly sets “Silo” apart is its skillful interweaving of various perspectives amidst a rigid political structure that thrives on tribalism and strategic ambiguity. After two seasons, the series plans to conclude its narrative in four seasons in total.

8. Cowboy Bebop

2021 saw Netflix debut a live-action version of the beloved anime titled “Cowboy Bebop.” Despite receiving unfavorable reviews from critics, it sparked renewed interest in the original series. The story takes place in 2071 and revolves around a team of bounty hunters aboard their ship, the Bebop. In the “Cowboy Bebop” universe, Earth has become largely uninhabitable due to a calamity linked to hyperspace technology, leading humanity to reside on various planets and moons throughout our solar system.

In simple terms, Shinichirō Watanabe, the creator and director of the original “Cowboy Bebop” series, coined the phrase “a unique blend of genres” for the show because it seamlessly combines elements from neo-noir, western, pulp fiction, and space opera. Much like many animated shows, “Cowboy Bebop” thrives at the junction of humor and emotion. The characters experience consistent development and often grapple with their past errors and sorrows, alongside the fresh adventures they embark on as a team of quirky bounty hunters.

7. Fallout

Bethesda Game Studios has been highly respected in the gaming world for many years, primarily due to hit series such as “The Elder Scrolls” and “Fallout.” Known for their meticulous detail, intense combat scenes, and darkly comic elements, it’s no wonder that the live-action TV adaptation of their “Fallout” universe has been so successful. The Amazon Prime version of “Fallout” has garnered widespread acclaim due to its talented cast (headed by Walton Goggins in a standout performance and the charming Ella Purnell), visually appealing balance, and witty humor.

If any aspect of the show veered off course, it could have collapsed entirely – maintaining a blend of witty humor and intense violence is challenging – however, the production harmoniously combines diverse elements like an expertly conducted orchestra. The “Fallout” universe offers a unique science fiction landscape, serving as both a potential future and an alternate reality. Before the nuclear war in the “Fallout” universe, technological and cultural growth didn’t progress at the same pace, resulting in game (and show) environments with a 1950s vibe, even though advanced technology such as robots, mech suits, and chemical enhancements are commonplace. The entire universe echoes Ray Bradbury’s short story “There Will Come Soft Rains.

6. Stargate: SG-1

During an earlier period, TV seasons used to consist of 20 episodes or more, even though they had lower budgets and simpler writing styles. However, this format provided viewers with a steady flow of storylines and details, making them more laid-back and generally more enjoyable to watch. “Stargate: SG-1” is one of the finest examples of this type of show in the science fiction genre, thanks to its 10 seasons filled with alien worlds, traditional sci-fi themes, strong protagonists, and adversaries with poor aiming skills. Although the 1994 film “Stargate” was quite serious, the series opted for a more lighthearted tone and became a popular choice within the genre.

In much-adored science fiction series like “Stargate: SG-1”, there are several aspects that some viewers opt not to question, despite their implausibility. This show isn’t designed for meticulous analysis, which can be frustrating for some, but it makes for an enjoyable viewing experience. Some of its standout episodes, such as “Window of Opportunity” in Season 4, are also some of the most humorous or self-referential. While deep reflections on the certainty of extinction and the inherent darkness within humanity hold merit, there are times when people simply want to watch a team of humans destroy spaceships and battle alien worms living in people’s minds – and that’s captivating.

Cast: Richard Dean Anderson, Michael Shanks, Amanda Tapping

5. Andor

Since Disney purchased Lucasfilm in 2012, they’ve launched numerous films and TV shows set within the “Star Wars” universe. Ranging from excellent (“The Mandalorian”) to questionable (“The Book of Boba Fett”) and even puzzling (“Star Wars: The Rise of Skywalker”), Disney’s “Star Wars” projects have predominantly been a collection of mediocre content. However, if the first two seasons of “The Mandalorian” hadn’t been exceptional, there might not have been any “Star Wars” entries on this list. But with “Andor,” Disney seems to have stumbled upon another gem.

This engaging spy series, titled “Andor,” set in the universe of “Star Wars,” delves into the early stages of the rebellion that ultimately brings down the oppressive Sith Empire as depicted in “Star Wars: Episode VI — Return of the Jedi.” The protagonist, Cassian Andor (played by Diego Luna), is a resourceful character who initially seeks to evade the authoritarian regime. However, he soon realizes that freedom from fascism is not an option.

The series provides a raw, enlightening portrayal of the Empire’s numerous atrocities and showcases the courage required by early rebels to challenge an apparently invincible power. It offers thought-provoking insights into politics and philosophy, all while utilizing its science fiction setting to explore darker themes that would be too grim in other contexts.

Cast: Diego Luna, Adria Arjona, Stellan Skarsgård

4. Arcane: League of Legends

2021 saw the debut of “Arcane: League of Legends,” commonly referred to as just “Arcane,” on Netflix. This series quickly gained a devoted fanbase due to its gripping narrative and unique blend of themes, appealing not only to fans of the online multiplayer game “League of Legends” (which serves as the universe for “Arcane”) and adult animation enthusiasts, but also drawing in many new viewers with its powerful storytelling.

Viewers found themselves captivated by the intriguing characters and engaging plot, which sparked extensive discussions and theories online. They particularly appreciated that these aspects didn’t hinder the show’s stunning visual effects. The series boasts a wealth of action, with fans highlighting their favorite fight scenes throughout the show, as well as an abundance of creative sci-fi elements. Despite only consisting of two seasons, “Arcane” has been met with universal acclaim, earning a perfect score on Rotten Tomatoes and ranking among Netflix’s most successful animated productions.

3. Star Trek: The Next Generation

The Original Series” is widely recognized and significant within the “Star Trek” universe, it’s not necessarily considered the best series produced by the franchise. Instead, many dedicated fans favor “Star Trek: Deep Space Nine,” but it’s challenging to argue that any “Star Trek” series has offered as much depth and satisfaction as “Star Trek: The Next Generation.

Under Captain Jean-Luc Picard, portrayed by Patrick Stewart on stage, at the helm of the USS Enterprise, “Star Trek: The Next Generation” skillfully blended the whimsical spirit of the initial series with a deeper sense of importance due to enhanced character depth and slightly more credible storytelling. In doing so, “Star Trek: The Next Generation” introduced fresh, well-integrated aspects into the narrative without deviating too much from the original series’ positive and forward-thinking atmosphere.

Cast: Patrick Stewart, LeVar Burton, Jonathan Frakes

Creator(s): Gene Roddenberry

Aired: 1987-1994 (7 seasons)

Where to watch: Paramount+

2. Battlestar Galactica (2003)

1978’s “Battlestar Galactica” TV show initially failed due to several factors, such as its expensive production and resemblance to “Star Wars,” which was the only movie from George Lucas’ original trilogy available at the time when “Battlestar Galactica” debuted. Despite having great potential, the series was released too early for its era. Fortunately, many Hollywood creatives recognized the story’s and characters’ value and revived the show in 2003 on the Sci-Fi Channel (renamed Syfy later).

The fresh version of the series immediately gained massive popularity, featuring numerous actors who received critical acclaim for their performances and high-quality production that managed to appear both lavish and authentic. “Battlestar Galactica” is a space saga primarily set on a fleet of spaceships housing the remnants of mankind, yet it’s also a gripping psychological drama. The fate of virtually every character hinges on life-or-death decisions because of humanity’s fragile existence, but what truly captivated viewers and characters alike was the enigma surrounding the identities of the final five Cylons, which kept everyone guessing throughout the series.

Cast: Edward James Olmos, Mary McDonnell, Katee Sackhoff

1. Doctor Who

From 1963-1989, the classic “Doctor Who” aired for 26 seasons, becoming a longstanding favorite of British TV viewers despite its modest budget. During its first two decades, the BBC was in such dire financial straits that they had to destroy numerous original episodes to reuse tape storage space. However, it’s the 2005 revival of “Doctor Who” that takes the crown on this list. The modern, revamped series, featuring Christopher Eccleston as the ninth portrayal of the Doctor, was an instant success when it premiered on British television.

In Season 2, Eccleston’s performance was exceptional, but it was David Tennant who truly captured the hearts of audiences worldwide with his portrayal of the unconventional, energetic, and morally righteous 10th Doctor. “Doctor Who,” a renowned science fiction series, offers an irresistible blend of time and space travel, encounters with intriguing alien species, thought-provoking concepts, and advanced technology. Moreover, the dynamic between the Doctor and his human companions adds depth and emotion to each episode. The 2005 revival of this show also skillfully blended long-term story arcs with standalone episodes, contributing to its status as not only the longest-running series on our list but also a significant milestone within sci-fi television.

Cast: Christopher Eccleston, Billie Piper, David Tennant, Matt Smith

Creator(s): Sydney Newman, C. E. Webber, and Donald Wilson

Aired: 1963-1989; 2005-present
