Warning: Spoilers ahead for Dexter: Original Sin season 1!With Dexter: Original Sin adding some much-needed context to the younger years of the franchise’s title character, the prequel show also manages to do so without falling victim to the same mistake as the original Dexter show. Although Patrick Gibson leads the Dexter: Original Sin cast as the infamous serial killer, original star Michael C. Hall is still heavily involved as he continues to perform narration duties as Dexter’s inner voice. The recasting of Dexter Morgan was an obvious and necessary move given when the new show is set, but this isn’t something the original project considered.
