When Dexter ended with its divisive finale in 2013, it seemed that was the nail in the serial killer’s coffin. Over a decade later, however, Showtime essentially became the Dexter network as spin-offs came out of the woodwork.Dexter: Original Sin was a nostalgic stab at the fan base in a series that showed a young Dexter (Patrick Gibson) joining Miami Metro and uncovering his potential as a killer of serial killers. Despite the marketable IP, Dexter: Original Sin was abruptly cancelled even though the network had promised another season. After Season 1, Showtime had greenlit the series only for the plug to be pulled months later.
