Particularly in recent years, there has been a boom in science fiction television, with numerous exciting and imaginative projects being produced. However, sci-fi is by no means a new sensation. Since pretty much the birth of television, it has been one of the most popular genres with general audiences, allowing them to immerse their imaginations in richly constructed alternate universes where anything is possible.

While the genre has always been popular, there's such a vast number and large variety of new sci-fi shows coming out every year that many outstanding series end up going unrecognized. Whether it's a very classic-style epic like Foundation, or even a subversive comedy like Resident Alien, there are plenty of underrated sci-fi shows that deserve a lot more recognition than they usually get.

20 'Fringe' (2008 - 2013)

Created by J.J. Abrams, Alex Kurtzman, and Roberto Orci

Fringe follows FBI agent Olivia Dunham (Anna Torv), scientist Walter Bishop (John Noble), and his son Peter (Joshua Jackson) as they investigate and try to rationalize mysterious and unexplained phenomena known as "the fringe." The series has some of the best seasons of television that have been aired in recent times, and never fails to be exciting even for those who aren't typically into the genre. For those who enjoy other underrated shows like Haven about solving ominous mysteries, Fringe is a perfect fit.

Fringe is action-packed, thrilling, and full of surprising turns, making up for its occasionally shaky storytelling. There is something for everyone because Fringe covers many scientific ideas including time travel, telepathy, parallel universes, and genetic engineering while blending procedural crime drama and science fiction components. The program, created by famous filmmaker J.J. Abrams, is said to be the ideal fusion of Lost and Alias (both also Abrams shows), offering fans of both programs a wonderful new alternative.

19 'The 4400' (2004 - 2007)

Created by René Echevarria and Scott Peters

Great new sci-fi TV shows are coming out all the time, but there's nothing quite like a good old 2000s classic. The 4400 is one of those tragic sci-fi TV shows that were canceled too soon. In it, as the reappearance of 4,400 missing persons on a single day confuses the global community, federal agents on the case slowly discover that the victims have been changed in dramatic ways. There are plenty of good stories about alien abductions, but not enough about the abductees being returned to Earth. The 4400 fills that void.

The 4400 became popular thanks to its innovative premise and ability to seamlessly weave creative sci-fi tropes into the deeply emotional aspects of the story. It delves into themes like identity and power, all set against the suspenseful backdrop of a Homeland Security investigation of a murder. The show was unfortunately canceled after four seasons, but it has since become a cult classic with a loyal following.

18 'Night Sky' (2022)

Created by Holden Miller

Night Sky, one of the best new space TV series, follows Irene (Sissy Spacek) and Franklin York (J. K. Simmons), an elderly couple in the Midwest who uncover a device that can teleport them to a chamber with a view of a strange, desolate alien planet. It's based on the quantum physics principle of quantum entanglement, which states that two particles are connected and affect each other even if they're light years away from each other.

Night Sky is a show that seamlessly switches between investigative drama, science fiction horror, and emotionally evocative life reflection. Though it was nuanced and had compelling characters and a smartly executed concept, making it one of the most underrated TV shows on Prime Video, Night Sky was unfortunately canceled after its first season due to low viewership. Nevertheless, its short run was enough to earn it a fair number of fans.

17 'Lexx' (1996 - 2002)

Created by Jeffrey Hirschfield, Paul Donovan, and Lex Gigeroff

The Canadian show Lexx started out as four made-for-TV movies, transforming into a traditional series after its success. Sexy, funny, and proud of its own weirdness, it's a cult classic about a group of disparate fugitives from an interplanetary tyranny, who find themselves in control of a massively powerful starship. What follows is one of the campiest pieces of media that fans of the genre will ever be able to find.

Its characters are fun, its plotlines are gripping, and its sense of adventure is exhilarating. Even when the show is busy being a self-aware romp full of innuendos and delightfully comedic premises, it always finds the time to pack in some surprisingly deep and even philosophical themes. It's one of the genre's most underappreciated classics.

16 'Lost in Space' (2018 - 2021)

Created by Matt Sazama and Burk Sharpless

The Netflix science fiction TV show called Lost in Space further proves that the streaming giant is a leading force in contemporary sci-fi television. The story follows the escapades of the Robinson family of space colonists whose ship deviates from its intended trajectory. The Swiss Family Robinson, a novel published in 1812, served as the basis for the original 1965 television series of the same name, which this modern rendition is based on.

Lost in Space is one of the best sci-fi shows on Netflix, thanks to a lot of intriguing characters that are easy to like and easy to relate to, which draws viewers in and makes them feel close to the show. The familial bonds that the narrative focuses on, in addition to the visually attractive alien continent with a wrecked spaceship and deadly robots, are the secret to the show's popularity and the reason it is so appealing to viewers outside the most ardent sci-fi fans.

15 'Raised by Wolves' (2020 - 2022)

Created by Aaron Guzikowski

Raised by Wolves centers on two androids called Father (Abubakar Salim) and Mother (Amanda Collin), who are assigned to care for human infants on planet Kepler-22b after a major battle decimated Earth. The androids then discover that regulating human beliefs is a perilous and challenging responsibility as the expanding colony of humans is threatened by religious divisions. Underrated sci-fi TV shows are aplenty, but they rarely get as fresh as this.

Raised by Wolves might be too bizarre for some viewers looking for a more grand sci-fi spectacle, but its visual marvel, mystery, and perpetual sense of danger are fascinating. Raised by Wolves is an intricate tale that's written with extraordinary imagination and flare, making remarks on topics like family, faith, and how artificial intelligence is taking over more and more aspects of human existence. Its cancellation after just two seasons is something that fans will never forgive.

14 'The Peripheral' (2022)

Created by Scott B. Smith

Set in a bleak yet chillingly familiar future where technology has changed society, The Peripheral follows a VR gamer, Flynne Fisher (Chloë Grace Moretz) as she explores a connection to an alternate reality. Along the way, she discovers details about a grim future of her own. Based on a thrilling novel by William Gibson, it's a thought-provoking examination of how technology impacts human relations.

A slow-burn sci-fi series, The Peripheral manages to paint a terrifying future in the subtlest of ways, which makes for a unique viewing experience. With a powerful performance from Moretz in what's arguably one of her best roles, the show had viewers eagerly awaiting a second season that unfortunately never came, as the series was canceled to fans' dismay. Still, its run was so fresh and original that viewers are sure to relish the show forever.

13 'Tales from the Loop' (2020)

Created by Nathaniel Halpern

Tales from the Loop is a beautiful sci-fi drama TV show based on Swedish artist Simon Stålenhag's art book of the same name. The show focuses on the townspeople who live above "The Loop", a scientific research facility that leads them to an alternate reality in which things that are impossible become attainable, thanks to a machine built to explore the mysteries of the universe.

Fans of the Netflix program Stranger Things may find Tales from the Loop's premise familiar, however, this series takes a more adult and serious tone. Tales from the Loop is a terrific option for curious viewers looking for the thought-provoking questions that sci-fi can bring up, because it is told with tenderness and care and features magnificent landscape compositions from filmmakers like Jodie Foster and Andrew Stanton. It's one of the best dystopian TV shows of the past few years, perfect for fans of the genre.

12 'Torchwood' (2006 - 2011)

Created by Russell T. Davies

Every now and then, TV show spin-offs can work wonderfully. Even then, despite being one of the most iconic and longest-running sci-fi shows of all time, Doctor Who had never had a spin-off — Until 2006. Russell T. Davies, who oversaw Doctor Who's 2005 revival, made Torchwood one of the most criminally underrated sci-fi TV shows of the 21st century. A sexier, more violent, and overall more mature show than its predecessor, it's about Captain Jack Harkness and his fellow members of a secret alien-fighting organization, protecting Earth from supernatural threats.

Though Torchwood in its earlier episodes was sometimes too desperate to prove that it was more grown-up than its older brother, it eventually found its voice — And what a voice it is. The series gave fans some of the creepiest aliens in the franchise, some of its most memorable characters, and a few of its most impactful episodes and stories. Viewers don't need to be Doctor Who fans to enjoy this sci-fi thrill ride.

11 'The Expanse' (2015 - 2022)

Created by Mark Fergus and Hawk Ostby

Based on James S. A. Corey’s series of novels of the same name, The Expanse is set in the near future, at a time when humanity dominates the Solar System. The story follows a group of characters who find themselves at the center of a plot that puts the system's precarious Cold War at a boiling point, while coping with existential issues brought on by recently found technology.

The show has six seasons, and each one balances a number of distinct genres that make it always feel fresh, intriguing, and fascinating. Throughout its epic narrative, The Expanse never shied away from depicting the atrocities people may commit in the name of authority, discrimination, or corporate greed, which is why it’s so awe-inspiring and powerful.

10 'Devs' (2020)

Created by Alex Garland

Film directors occasionally dip their toes into television, and when they do, they can only hope that the result will be as outstanding as Devs. It's a sci-fi thriller miniseries created by Alex Garland that follows software developer Lily Chan (Sonoya Mizuno), who works for Forest’s (Nick Offerman) quantum computing business. Lily quickly becomes involved in her boyfriend's unexplained murder, which occurred on his first day at a new job at Devs.

Similar to Garland's previous work, the show is incredibly stylish, with lively music and dreamy visuals. Moreover, the murder mystery premise is accompanied by philosophical ideas that are so profound and esoteric that it may be challenging for many viewers to fully comprehend. Sci-fi fans should add the series to their watchlist since it brilliantly portrays the unsettling, almost religious influence of tech giants that appear to dominate every aspect of people's lives.

9 'Future Man' (2017 - 2020)

Created by Kyle Hunter, Howard Overman, and Ariel Shaffir

Future Man is a comedy sci-fi TV show that follows a janitor named Josh Futturman (Josh Hutcherson) who is underachieving at work, but can easily beat his favorite and undefeatable video game, Biotic Wars. Suddenly, the game's two main characters, Tiger (Eliza Coupe) and Wolf (Derek Wilson), suddenly arrive and ask Josh for help in defending the planet from the actual Biotic Wars.

Viewers may feel drawn into the narrative and transported back in time by the show's vibrant color scheme and retro design. What makes Future Man particularly captivating is the character-driven action, as opposed of the normal event-based tropes that viewers often see in shows like this, adding depth to the program and balancing the hilarious gags with some exquisite dramatic moments and character development.

8 'Alice in Borderland' (2020 - 2022)

Created by Haro Aso

Alice in Borderland is a Japanese Netflix series about a group of friends led by an obsessed gamer who are suddenly transported to a strange emptied-out version of Tokyo in which they must play deadly games to survive. They're all given "visas" that accrue points, and any player who runs out is immediately disqualified and killed. They soon find that things are more sinister than they seem.

The show is addictive thanks to its intense action sequences, suspenseful story, incredible actors, complex world-building, and exploration of themes like friendship, survival, and power. An incredible and complex death game show, Alice in Borderland is consistently finding more and more inventive ways to explore the reality that the players are forced to deal with, and leaves viewers with more questions than answers (in the best way possible).
