Superman has been a cornerstone of pop culture for generations—appearing in countless feature films, animated shows, live-action series, and comic book crossovers. But in 2018, DC tried to expand the Man of Steel’s mythos in a bold new way—with Krypton, a prequel series focused on Superman’s grandfather and the political drama of his doomed home planet. Billed as DC’s answer to Game of Thrones, the show aimed to deliver epic storytelling, rich world-building, and a new corner of the DC Universe. Instead, Krypton struggled to find its audience and was canceled after just two seasons.
