Legion already separates itself from other superhero shows through its use of a largely character-driven story and departure from long-winded exposition. The first episode takes its audience on a visually stunning journey as it diverges from typical superhero tropes and commits to its unique style. The series follows the journey of David Haller (Dan Stevens), a young man being treated in a mental hospital after being diagnosed with schizophrenia and attempting suicide. The causes of his illness are vague as he is also a mutant with telepathic and telekinetic powers. While he is undoubtedly able to move things and cause serious damage with his mind, it is unclear whether the voices in his head are entirely hallucinations or if they are a result of his mind-reading abilities.
