The cliffhanger ending of season 12 proves why Ryan Murphy's American Horror Story is still such an engaging and intriguing horror series. In the years since the show's 2011 premiere, AHS has explored ghosts, clowns, creepy hotels, a writer's strange time in a beach town, and a family's lives being ruined when they move into an eerie old house. American Horror Story season 12, called Delicate, aired from September 2023 to April 2024 and focused on the twists and turns of Anna Victoria Alcott's (Emma Roberts) pregnancy.
