Calling a TV show a masterpiece is no small feat. While some series are flawless from start to finish, others earn the title through sheer ambition, emotional resonance, and a devoted fanbase. In the vast landscape of science fiction, a handful of underrated gems have quietly achieved masterpiece status, even if mainstream audiences overlooked them. Here are eight sci-fi shows that are truly underrated masterpieces, from start to finish.
12 Monkeys (2015–2018)
Terry Gilliam's 1995 film 12 Monkeys is often considered untouchable, so when SYFY announced a TV adaptation, skepticism ran high. Surprisingly, the series turned out to be a coherent, thrilling time-travel saga that expanded on the film's concepts. Starring Aaron Stanford as time traveler James Cole and Amanda Schull as virologist Cassie Railly, the show follows Cole's mission from a post-apocalyptic 2043 to 2015 to stop the Army of the 12 Monkeys from releasing a deadly virus. Despite an initially mixed reception, the series grew in popularity thanks to its airtight storytelling and satisfying four-season arc. Its relatively unknown cast and lack of marketing may have kept it under the radar, but 12 Monkeys comes remarkably close to perfection.
Fortitude (2015–2018)
You might not immediately think of Fortitude as sci-fi, but this psychological thriller set in a remote Arctic town blends horror, mystery, and body horror with subtle sci-fi elements. The show immerses viewers in its icy, claustrophobic atmosphere so effectively that you'll want a blanket while watching. When the safest community on Earth experiences its first murder, Sheriff Dan Anderssen (Richard Dormer) uncovers a chilling conspiracy. With a stellar cast including Stanley Tucci, Christopher Eccleston, and Michael Gambon, Fortitude is a masterclass in tension and atmosphere that deserved far more attention.
Travelers (2016–2018)
Netflix's Travelers is so underrated that many haven't even heard of it. This character-driven series follows operatives from a distant future who inhabit the bodies of people about to die in the present, working to prevent catastrophic events. With tight writing, intricate time-travel rules, and a focus on humanity, the show earned critical praise across its three seasons. Eric McCormack, MacKenzie Porter, and Nesta Cooper lead a cast that makes every episode engaging. If you're looking for a rewatchable sci-fi gem, Travelers is a must-see.
Orphan Black (2013–2017)
Though it developed a cult following known as the Clone Club, Orphan Black remains underrated in the broader TV landscape. Tatiana Maslany delivers a tour-de-force performance as multiple distinct clones, each with her own personality and quirks. The series blends cloning, corporate espionage, and bioethics into a gripping conspiracy thriller. Sarah, a con artist, stumbles into a world of identical strangers and must navigate a dangerous web of secrets. Maslany's transformative acting earned her an Emmy, and the show's exploration of identity and ethics makes it a true masterpiece.
Counterpart (2017–2019)
Starz's Counterpart is one of the best espionage thrillers of the past decade, with a brilliant sci-fi twist: a parallel universe. J.K. Simmons plays a low-level bureaucrat who discovers his world has a mirror counterpart, leading to a Cold War-style conflict between the two realities. The show expertly weaves themes of identity, conspiracy, and moral ambiguity, much like Severance but with more spy action. Its two-season run is a tight, compelling narrative that deserves a spot on any sci-fi fan's watchlist.
The OA (2016–2019)
Netflix's The OA is a cult classic that divided audiences but earned a passionate following. The series follows Prairie Johnson, a blind woman who returns after seven years with her sight restored and a mysterious story to tell. Blending metaphysical sci-fi with emotional drama, the show explores near-death experiences, alternate dimensions, and the power of storytelling. Though canceled after two seasons, its ambitious narrative and haunting performances make it an underrated masterpiece.
Dark (2017–2020)
German series Dark is a mind-bending time-travel saga that weaves together four families across multiple generations. Its intricate plot, atmospheric setting, and philosophical themes earned it comparisons to Stranger Things, but Dark is far more complex and rewarding. The show's three-season arc is meticulously planned, delivering a satisfying conclusion that ties up every loose end. If you enjoy puzzles and deep storytelling, Dark is a must-watch.
Fringe (2008–2013)
Though it had a loyal fanbase, Fringe never achieved the mainstream recognition it deserved. This sci-fi procedural follows an FBI team investigating bizarre phenomena, gradually uncovering a larger conspiracy involving parallel universes and a war between worlds. With strong character development, inventive storytelling, and a perfect blend of monster-of-the-week and serialized arcs, Fringe is a masterclass in genre television. Its five-season run is a testament to its enduring quality.
These eight shows prove that underrated doesn't mean unworthy. Each one offers a unique vision, compelling characters, and a story that sticks with you long after the credits roll. Whether you're a die-hard sci-fi fan or just looking for something new, these masterpieces deserve a spot on your watchlist.
