Based on the X-Men comics character, David Haller (Dan Stevens) was diagnosed as schizophrenic as a child and currently institutionalized. His routine at a psychiatric hospital is changed with the arrival of a new patient named Syd (Rachel Keller) which triggers the discovery that the voices and visions he has may be real.
What The Critics Say (Metascore 82)
  • Legion presents a superhero drama as psychic journey, distinguishing itself in an overcrowded genre by setting its most compelling drama in its protagonist’s mind. It’s no ordinary comic-book show: it’s a head trip, and it’s spectacular. — James Poniewozik, New York Times
  • It’s a delight, existing so far outside the mold of recent superhero adaptations in the 2010s that it couldn’t see the mold even with telescopic vision. It’s a comic book show likely to be as appealing to people who have no interest in comic books as to those who can name David’s famous relative without Googling, if not more, and it’s easily the most exciting new series this young year in TV has offered so far. — Alan Sepinwall, UPROXX
  • If any show deserves your patience, it’s Legion. Rewards await. — Robert Bianco, USA Today
