The planned second season of the ‘Dexter’ prequel series ‘Dexter: Original Sin’ has been canceled. The network’s parent company Paramount recently merged with Skydance, which may explain why the prequel series was canceled. ‘Dexter: Original Sin’ was set in 1990s Miami and starred Patrick Gibson as a younger version of the titular serial killer, with Christian Slater portraying his police detective father, Harry. The news comes as sequel series, Dexter: Resurrection, starring Michael C. Hall, is winding down its first season on Showtime and Paramount+. That show is expected to return for a second season.
