Forget Lost, FX's 27-Episode Mystery Box Masterpiece Series Doesn't Waste A Single Scene

Tom is based in the UK and when he's not writing about TV shows, he's watching them. He's also an avid horror fiction writer, gamer, and has a Dungeons and Dragons habit that he tries (and fails) to keep in check.

The impact of Lost on the entertainment landscape can’t be overstated. Not only was it a ratings juggernaut, the ABC series transformed mystery-box sci-fi into a mainstream TV genre. Audiences in their millions spent six seasons debating the meaning of the hatch, the Smoke Monster, the numbers, and the Island itself, long before the era of streaming and fandoms. It established the blueprint for addictive shows that delivered questions faster than answers, and to this day countless sci-fi series still follow Lost’s formula.

However, Lost’s influence doesn’t make it flawless. There’s at least one low to every high point of its 121 episodes, with some storylines feeling far less essential than they should be. It becomes particularly noticeable when compared to a shorter and much tighter mystery box sci-fi series that arrived seven years after Lost ended. FX’s Legion took the same obsession with uncertainty and unreliable information and compressed it into just 27 episodes, creating something far more controlled without sacrificing ambition or strangeness.

Based on the Marvel Comics character of the same name, Legion brings Dave Haller (Dan Stevens), an immensely powerful mutant from X-Men, into live action as he discovers his perception of reality cannot be trusted. Creator Noah Hawley turns the superhero source material into an elaborate psychological sci-fi mystery neatly wrapped in three expertly-crafted seasons. Its tightly constructed plot makes practically every scene feel deliberate, rather than being the collage of hit-and-miss moments that Lost’s sprawling saga can be.

Unlike Lost, Legion Has No Skippable Episodes

For all Lost’s greatness, its enormous episode count has led to a lot of sub-par installments. The show was groundbreaking overall, but episodes like “Stranger in a Strange Land” and “Fire + Water” contribute basically nothing on a rewatch. Legion simply doesn’t have that problem.

Despite it being a notoriously psychedelic viewing experience, the 27 episodes of Legion are all important chapters in a concentrated and cohesive story, with the many visual experiments carrying hiding information that becomes apparent later on. David’s memories, the shifting architecture of Summerland, Oliver Bird’s (Jemaine Clement) strange astral existence, and the increasingly surreal manifestations surrounding Amahl Farouk (Navid Negahban) aren’t just surrealism for surrealism’s sake. The uncertainty is essential to the narrative.

As David becomes increasingly unreliable the importance of the weirdness to the mystery starts to become crystal clear. The meaning of Legion’s most abstract scenes changes alongside what is revealed about David, Farouk, and the nature of their conflict. Apparent narrative detours in early episodes are later revealed as important clues to a character’s psychology or the distorted reality surrounding them, all of which feeds into the overarching narrative.

For mystery box fans, this density and lack of filler makes Legion exceptionally satisfying to revisit. Lost offers a much larger world and more characters, but that scale also creates disposable stretches. Legion is built more like a 27-chapter puzzle: removing one piece risks losing something important. Every episode is essential, every scene deliberate, making for arguably a much more satisfying viewing experience than Lost, especially when it comes to rewatches.

Legion Is A Masterclass In Superhero Storytelling

Legion isn’t only an expertly constructed sci-fi mystery box series. It is also one of television’s most unusual comic book adaptations because it refuses to behave like a conventional superhero show. David possesses extraordinary psychic abilities, yet Legion doesn't see him using them to save the day. Powers like telepathy, telekinesis, astral projection, and reality manipulation aren’t used to fight criminals but as ways for the series to blur the boundary between what’s real and what isn’t.

It’s an approach that perfectly suits David as a character. In Marvel Comics, Legion is the mutant son of Charles Xavier whose immense powers and fractured psyche make him one of the X-Men universe’s most unpredictable, and powerful, figures. Noah Hawley keeps the fundamentals, but Legion never becomes another straightforward X-Men story. Instead, it’s a story about a man (who just so happens to be a mutant with superpowers) trying to navigate a psychedelic world where identity and reality themselves are unstable.

This makes Legion unusually introspective for a superhero TV show. Its conflicts aren’t physical fights between a hero and a villain. They’re philosophical explorations into ideas like control, perception, morality, and trauma, all of which are anchored by David’s increasingly disturbing belief that his abilities justify his actions. Superpowers aren’t simply weapons used during climactic battles; they fundamentally alter how the story is told and how confidently viewers can trust anything appearing onscreen.

Legion’s experimentation helped pave the way for the wave of avant-garde and stranger superhero TV shows that followed. Doom Patrol would similarly embrace surrealism, damaged characters, and absurd concepts, and the MCU’s WandaVision later used shifting television formats to depict its own distorted reality. Then there’s the upcoming VisionQuest, which will partially be taking place inside an AI mindscape and promises to be one of the surrealest and introspective superhero TV shows so far. Before all of them, Legion had already demonstrated how far superhero TV could move beyond conventional costumed fights.
