Plot
Miami, 1991
When his bloodlust can no longer be ignored, young Dexter Morgan must learn to channel his inner darkness as he goes from student to avenging serial killer with the guidance of his father, Harry. older than James Remar when Dexter (2006) first aired. Followed by Dexter: Resurrection (2025). Dexter: Original Sin takes a bold gamble, revisiting Dexter Morgan’s formative years and offering a fresh perspective on his dark passenger.
Its greatest strength is its casting
While some prequels stumble under the weight of established canon, Original Sin largely succeeds, enriching the Dexter mythology while offering a compelling, standalone story. Patrick Gibson, while initially a questionable choice, grows into the role of young Dexter, capturing the character’s signature blend of social awkwardness and chillingly calculated violence. Molly Brown shines as Deb, infusing the younger version of the character with a fiery spirit and vulnerability that resonates deeply. The supporting cast, including Alex Shimizu as Masuka and James Martinez as Batista, also deliver strong performances, effectively capturing the essence of their original counterparts.
Original Sin is not without its flaws
Christian Slater, however, feels a bit out of place as Harry, who struggles to fully embody the character’s internal conflicts. The series deftly weaves together familiar elements from the original Dexter, including iconic musical cues and visual motifs, while also exploring new territory. The plot involving Harry’s deceased son adds a level of complexity to Dexter’s origin story, even if it occasionally veers into melodramatic territory. The central mystery surrounding Dexter’s current predicament at Iron Lake provides a compelling plot, keeping the tension high throughout the season.
The pacing can be uneven, with some episodes feeling rushed while others drag
The show’s overreliance on licensed music occasionally clashes with its darker themes. And while the CGI has generally improved since the first episode, some scenes still suffer from notable visual effects issues. Despite these shortcomings, Dexter: Original Sin is a worthwhile addition to the Dexter universe. It’s a darkly entertaining exploration of Dexter’s past that offers a fresh perspective on his transformation into the Bay Harbor Butcher.
