Why it is one of the best sci-fi TV shows: From creator Dan Erickson and executive producer Ben Stiller, Severance is one of the most inventively bizarre, absorbing, and simply best TV shows on Apple TV+, let alone in recent memory, and has a highly anticipated second season in the works.

The adventures of a crew of bounty hunters in space in the distant future.

Quantum Leap (1989-1993)

A freak accident sends a brilliant scientist (Scott Bakula) on a journey inhabiting the bodies of strangers from different time periods to right wrongs of the past.

Why it is one of the best sci-fi TV shows: Later rebooted for modern audiences with Raymond Lee in the lead, Quantum Leap is one of the most unique stories about time travel ever conceived, and only made greater by the wonderful chemistry between Bakula and the late Dean Stockwell as his holographic guide, Al.

Why it is one of the best sci-fi TV shows: Showrunner Graham Yost’s adaptation of Hugh  Howey’s bestselling book series is a wonderfully suspenseful dystopian treat, especially with killer performances by the Silo cast, which also includes Common, Tim Robbins, Rashida Jones, and more.

Black Mirror (2011-Present)

The best Black Mirror episodes so far include futuristic cautionary tales, morality dramas, and even bizarre supernatural fantasies.

Why it is one of the best sci-fi TV shows: This list is meant to highlight science-fiction shows, but most stories featured in Charlie Brooker’s Netflix exclusive, technophobic horror anthology series, Black Mirror, feel almost too frighteningly plausible to be considered “fiction.”

Stream Black Mirror on Netflix.

Firefly (2002-2003)

Centuries after mankind left Earth to colonize the rest of the galaxy, a ragtag crew of smugglers and fugitives led by a rebellious ship’s captain (Nathan Fillion) offer their services to those in need while on the run from the government.

Why it is one of the best sci-fi TV shows: Oddly enough, most sci-fi series with the most devoted fan bases are the kind of shows that were cancelled too soon, like Firefly –  a groundbreaking of space operas with the Western, which later spawned a feature-length follow-up called Serenity.

Why it is one of the best sci-fi TV shows: Despite being a crude, blatant send-up of Back to the Future at its surface, co-creators Dan Harmon and Justin Roiland (who formerly voiced to title characters) made Adult Swim’s Ricky and Morty into something special that many consider to be one of the best animated TV shows of all time.

Why it is one of the best sci-fi TV shows: From creator Jon Favreau, the Emmy-winning Disney+ exclusive series, The Mandalorian, is unique to previous stories to come from a galaxy far, far away for its western-style tone, moving, character-driven plot, and, above all, the cutest alien baby you have ever seen.

The X-Files (1993-2018)

Two FBI agents (David Duchovny and Gillian Anderson) investigate cases a little stranger than your typical homicide – such as alien abductions, interspecies mutation, or extra sensory perception, among other things.

Why it is one of the best sci-fi TV shows: Originally lasting nine seasons before its two-season revival in 2016, creator Chris Carter’s Emmy-winning hit The X-Files has the tone of a crime procedural and pulse of an eerie midnight movie, resulting in one of the genre’s most exquisitely constructed and phenomenally original creations.

Twin Peaks (1990-2017)

A special agent of the FBI (Kyle McLachlan) is sent to investigate the death of a young woman in a small Washington town, which proves to be the site of an even stranger variety of mysteries.

Why it is one of the best sci-fi TV shows: Winner of the Golden Globe for Best Drama Series in 1991, creators David Lynch and Mark Frost’s Twin Peaks became a touchstone of addictive episodic television in only two seasons before its short 2017 revival on Showtime for its unprecedented idiosyncrasies and delicious surrealism.

The crew of the U.S.S. Enterprise-D continues Starfleet’s exploration of uncharted areas of space.

Why it is one of the best sci-fi TV shows: Widely considered to be a spin-off as good as the original – or even the strongest iteration of Gene Roddenberry’s iconic franchise overall – is the multi-Emmy-winning Star Trek: The Next Generation, especially with Sir Patrick Stewart as Enterprise captain Jean-Luc Picard.

Stream Star Trek: The Next Generation on Paramount+.
Stream Star Trek: The Next Generation on Pluto TV.

The Expanse (2015-2022)

In an entirely colonized and seemingly peaceful solar system, a space freighter crew makes a dark discovery that gives them a reason to rebel and become heroes.

Why it is one of the best sci-fi TV shows: Based on James S.A. Corey’s celebrated novels, The Expanse is lauded by critics and audiences alike as one of the best sci-fi TV shows on Amazon Prime and one of the genre’s smartest shows of its time in general.

Stream The Expanse on Amazon Prime.

The Twilight Zone (1959-1964)

A collection of fantastic, mind-bending character studies that are often reflective of the pressing matters from the era.

Why it is one of the best sci-fi TV shows: While it would later inspire multiple reboots, most would agree that nothing beats Rod Serling’s original classic anthology series, The Twilight Zone, in terms of its outstanding depth and imagination.

Stream The Twilight Zone on Paramount+.

The Jetsons (1962-1987)

An average family gets themselves into bizarre situations in a futuristic utopia.

Why it is one of the best sci-fi TV shows: After receiving (probably inaccurate) lessons about the Stone Age from Hanna-Barbera, children could also indulge in the animation studio’s vision of the future with The Jetsons – one of the most beloved marriages with the traditional sitcom structure with the sci-fi genre.

Stream The Jetsons on Max.
Stream The Jetsons on Tubi.
