The apex of the original Dexter series came at the end of Season 4, featuring John Lithgow in a season-long guest appearance as the Trinity Killer. By that time in the series, Dexter had evolved to the point where he had a wife, and a baby boy named Harrison, and, in most respects, a normal family life. Except that, as Dexter hunted the Trinity Killer, the Trinity Killer was hunting him — and ended up killing Dexter’s wife, and leaving their son in a pool of his mother’s blood, traumatized just as Dexter had been as a child. Showrunner Clyde Phillips, who had overseen the series for four seasons, walked away after that season finale — which I always considered the perfect ending for the series.
Except it didn’t end. Without Clyde Phillips, Dexter kept going, for several more seasons, none of them any good. Eventually, Clyde Phillips returned to the franchise with two more “Dexter” series — a prequel called Dexter: Original Sin, and a sequel, Dexter: New Blood. That show reintroduced Dexter’s son Harrison, now as a homicidal teenager — who, in the finale, shot Dexter dead with a hunting rifle.
But as we learned in the opening episode of the new Paramount+ and Showtime series Dexter: Resurrection, also developed by Clyde Phillips, Dexter was shot, all right — but not shot dead. Instead, we found him in a 10-week coma, subject to a series of drug-induced dreams. He’s visited in those dreams by several familiar faces from his past — including John Lithgow as the Trinity Killer.
