The FX on Hulu drama Y: The Last Man is the latest in a long line of post-apocalyptic narratives of TV, but this one comes with a novel twist: A mysterious event wipes out every mammal on Earth with a Y chromosome, except for two: an aimless would-be escape artist named Yorick, and his companion monkey, Ampersand. In a world overrun by militias and fueled by paranoid conspiracy theories, a beleaguered government attempts to rebuild — and keep certain secrets from getting out.
