25 Underrated Sci-Fi TV Shows That Deserve Your Attention

By Richard Chachowski · September 22, 2023, 7:41 AM EDT

Like the kaleidoscopic worlds they're frequently set in, the sci-fi genre is an almost bottomless ocean of books, comics, movies, and TV shows — many of which are worth seeing or reading for one reason or another.

With how many sci-fi TV shows exist, it seems inevitable that dozens of great series fail to capture mainstream audience attention on par with Battlestar Galactica or Star Trek.

From cult space operas to overlooked gems from the UK, here are 25 of the best, most underrated sci-fi TV series ever made.

Across the globe, ordinary people begin to discover that they have superhuman abilities. These individuals include an indestructible Texas cheerleader (Hayden Panettiere), a Japanese office worker who can teleport (Masi Oka), and a serial killer able to absorb other people's powers (Zachary Quinto).

Ignoring the disastrous final two and a half seasons, you're left with a taut, realistic superhero show that nearly dethroned Lost in its exceptional first two seasons.

A continuation of the 1983 miniseries and its follow-up, V: The Final Battle, V is a bold and imaginative space opera start-up in the same overly stylized mold as Star Wars (in the best way imaginable, of course).

In the near future, a depressed human detective (Karl Urban) is assigned an android partner (Michael Ealy), their professional relationship slowly blossoming into friendship.

A wonderfully written musical comedy, Dr. Horrible's Sing-Along Blog skewers the superhero genre in two, coming across a more adult version of Megamind.

This little-known British export may not have much of a fanbase in the States, but its success speaks for itself: 12 seasons, four novels, and even a magazine that ran from '92 to '94.

Though that premise may sound comedic, the joy of Planetes is its basis in hard science and its heavy focus on existential themes.

In 2199, Earth has been turned into a radioactive wasteland by an invasive alien race. In desperate need of an environment to sustain them, the spaceship Yamato travels to the planet Iscandar, believing the planet has the means to make their home hospitable again.

Released in 1974, Space Battleship Yamato 2199 has regularly been one of the most influential anime series there is, inspiring everything from Mobile Suit Gundam and Neon Genesis Evangelion to the iconic video game sensation, Space Invaders.

Whenever a remake of a beloved '60s show premieres, there's bound to be a comparison between the original and the remake. Hinging heavily on its emotional undertones, though, Lost in Space does much to set itself apart from its earlier counterpart.

The Wild Wild West

In a steampunk version of the Wild West, two government agents ( Robert Conrad and Ross Martin) travel the frontier, ridding the land of any dangerous threats they come across.

Designed to be a Western version of James Bond (complete with wacky gadgets, physically imposing henchmen, and dastardly villains), it's one thousand times better than that godawful Will Smith movie.

Final Space

While working off his prison sentence, astronaut Gary finds companionship in a mysterious yet adorable alien — who also happens to be one of the most dangerous creatures in the universe.

Brimming with an all-star cast (David Tennant, Steven Yeun, Fred Armisen, Conan O'Brien, Jane Lynch, and Keith David), Final Space starts off as your typical Adult Swim comedy before slowly morphing into an out-and-out space opera of epic proportions.

Nearly a century after a nuclear war has ended civilization on Earth, the remnants of humanity send 100 troubled youths to the world's surface in the hopes of reestablishing humankind’s presence on the planet.

A post-apocalyptic version of Lord of the Flies, The 100 is an acquired taste for some, but those who love a good, teen-driven drama won't be disappointed.

The OA

Having gone missing seven years ago, a blind young woman named Prairie (Brit Marling) returns home, her eyesight somehow completely restored.

Canceled at the worst time imaginable, leaving infuriated fans with an unresolved cliffhanger, The OA has regularly been called one of the best sci-fi shows of all time by publications like Empire, Wired, and BBC.

Resident Alien

Resident Alien‘s greatest strength is always entertaining Alan Tudyk, but more than that, it's an unexpectedly emotional look at a very different kind of alien invasion.

Orphan Black

After witnessing the suicide of a woman who looks exactly like her, the street-savvy Sarah (Tatiana Maslany) decides to take the woman's place, pulling her into a world of sinister conspiracies around every corner.

Cloneliness is Next to Godliness?

In her transformative performance as Sarah, Maslany propels Orphan Black to sci-fi heights, the show existing an intense and intelligent meditation on cloning and the ethics (or lack thereof) involved in the process.

The Venture Bros.

Once a famous boy inventor, Dr. Rusty Venture has since grown up to be a depressed, crotchety middle-aged mad scientist. Together with his two less-than-intelligent sons and their burly bodyguard, the four embark on numerous adventures the world over.

Jonny Quested

A spoof of classic '60s Hanna-Barbera cartoons like Jonny Quest, The Venture Bros has amassed a significant following since its 2003 debut. However, even the most dedicated of fans can't deny it tends to be overshadowed by more recent Adult Swim series like Rick and Morty.

Babylon 5

In the 23rd century, the galaxy is once again beginning to stabilize after a massive war between the Earth Alliance and the Minbari. Stationed at a strategic neutral zone is the station Babylon 5, a site of political intrigue and maneuvering by both sides of the conflict.

Last Outpost for Peace

If ever you were looking for a more political space opera, this is it. Tackling such themes as political factions, cold war power struggles, and racism, Babylon 5‘s reputation among sci-fi enthusiasts has only improved with time.

Future Boy Conan

Twenty years after World War 3, the remnants of mankind live on a chain of islands as they slowly try to rebuild society. In the middle of it all is Conan, a 12-year-old boy with superhuman strength trying to find an 11-year-old girl who's been kidnapped by the insidious forces of Industria.

A very early work from anime giant and Studio Ghibli founder, Hayao Miyazaki, Future Boy Conan bears all the charm and imagination of Miyazaki's later work, serving as a direct precursor to his breakthrough Castle in the Sky.

A deft blend between space opera and neo-noir, The Expanse is a rich mystery series wrapped around an audacious sci-fi war story — one that may rival the likes of Stargate SG-1 or Babylon 5.

The Prisoner

After he abruptly resigns from his post for an unknown reason, a British secret agent (Patrick McGoohan) wakes up at a bizarre, idyllic coastal village policed by an unknown group.

What The X-Files did for government conspiracy theories, Fringe does for fringe science. Delving into an expansive mythology as rich as Supernatural's, it's the best monster-of-the-week show you've never seen.

Nowadays, it seems almost a given that any list of underrated sci-fi shows ends with Firefly. Unjustly canceled after a single season, it's continued to live on in the form of numerous comics, board games, and a feature film continuation.
