Legion season 3

The third and final season of the American surrealist superhero thriller television series Legion premiered on FX on June 24, 2019, and concluded August 12, totaling eight episodes. The series is based on the Marvel Comics character David Haller, a mutant diagnosed with schizophrenia at a young age, who learns that his illness may actually be powerful psychic abilities. In the final season, David recruits a time-traveling mutant to help him rewrite the past to fix his life, all while his former friends hunt him down. It was produced by FX Productions in association with Marvel Television, with Noah Hawley serving as showrunner.

Dan Stevens stars as David, with Rachel Keller, Aubrey Plaza, Bill Irwin, Navid Negahban, Jeremie Harris, Amber Midthunder and Hamish Linklater also returning from previous seasons to star. They are joined by newcomer Lauren Tsai. Legion's third season was ordered by FX in June 2018, and was confirmed to be the final season in February 2019. The season's set design and costumes drew heavy inspiration from the psychedelia aesthetic of the 1960s and 70s, and more musical sequences were integrated into the narrative.

The season received critical acclaim, with many praising its visuals, themes, use of music, performances, and sense of closure. Many deemed it a satisfying conclusion to the series, though some criticized the pacing of the final two episodes.
