Forget the weak later seasons and that laughable ending, the first four years of Dexter were thrillingly dangerous TV.
Dexter Morgan (Michael C Hall), a mild-mannered forensic bloodstain pattern analyst for the Miami Metro Police Department, secretly led a double life as a serial killer with a code – he only took out other murderers.
Driven by an internal, uncontrollable urge to kill (which he called his “Dark Passenger”), Dexter avoided capturing innocent people by strictly adhering to a set of rules called “Harry’s Code”, which was taught to him by his adoptive father, Harry Morgan (James Remar), a Miami police detective who recognised Dexter’s sociopathic tendencies stemming from childhood trauma.
Under this code, Dexter must target only guilty murderers who had escaped the traditional justice system, find absolute, undeniable proof of their guilt before acting, and never get caught – which led him to craft meticulous, plastic-wrapped “kill rooms” and dispose of dismembered remains in the ocean.
Dexter was an ambiguous figure, though, and you genuinely never knew which way he would turn or if his “friends” and family were truly safe. His cynical, deadpan inner monologue narrated the series.
Debra Morgan (Jennifer Carpenter) was Dexter’s foul-mouthed, fiercely loyal adoptive sister who rose through the ranks of Miami Metro Homicide, completely unaware of his secret life.
His other colleagues at Miami Metro included the good-natured Sergeant Angel Batista (David Zayas), ambitious Lieutenant Maria LaGuerta (Lauren Vélez), and the crude forensic technician Vince Masuka (C.S. Lee).
The first season – directly adapted from Jeff Lindsay’s 2004 novel Darkly Dreaming Dexter – was intense, as Dexter hunted the Ice Truck Killer, a theatrical murderer who targeted sex workers and left bloodless, frozen body parts across Miami (leading to a shocking personal revelation).
Dexter’s underwater dumping ground was discovered in season two, sparking a massive FBI manhunt for an unidentified serial killer dubbed the “Bay Harbor Butcher”.
But Dexter’s pursuit of Arthur Mitchell (John Lithgow) – a.k.a. the “Trinity Killer” – in season four was the show’s high point.
Dexter became so obsessed with the Trinity Killer that he held off killing him so he could learn how he managed to maintain both his darkness and his family life. By the time Dexter got close enough, he realised not all was what it seemed.
He would forever regret his decision not to kill Arthur right away when he arrived home after the eventual satisfying kill to find his wife Rita (Julie Benz) dead in the bathtub – murdered by Arthur as a parting gift before he himself was killed.
The show increasingly explored themes of religion, trauma, and the unravelling of Dexter’s secret, eventually culminating in a highly controversial series finale in season 8.
The show was a massive hit for Showtime and has since expanded into a broader television universe, including the 2021 limited-series sequel Dexter: New Blood, the prequel Dexter: Original Sin, and the follow-up Dexter: Resurrection.
