Following the success of Dahmer, Ryan Murphy and Ian Brennan's true-crime anthology series is back with Monsters: The Lyle and Erik Menendez Story. The pair were convicted in 1996 for murdering their parents, José and Mary Louise “Kitty” Menendez -- with the show promising to dive "into the historic case that took the world by storm, paved the way for audiences' modern-day fascination with true crime, and in return asks those audiences: Who are the real monsters?" The show debuts September 19 on Netflix.
