Dexter is an American television series that aired from 2006 to 2013 on Showtime. Based on the novel Darkly Dreaming Dexter by Jeff Lindsay, the show follows Dexter Morgan, a blood-spatter analyst for the Miami Metro Police Department who leads a secret life as a vigilante serial killer. Plot Summary Dexter Morgan, portrayed by Michael C. Hall, is shaped by a traumatic childhood event that leaves him with a compulsion to kill. Rescued and adopted by Harry Morgan, a Miami police officer, Dexter is trained to channel his dark urges into a strict moral framework called "The Code of Harry." This code dictates that Dexter only kills people who have committed heinous crimes and escaped justice, while ensuring he never gets caught. Despite claiming to lack emotions, Dexter forms complicated relationships, particularly with his adoptive sister Debra Morgan (played by Jennifer Carpenter), a dedicated police officer. Throughout the series, Dexter struggles to balance his facade of normalcy with his inner darkness. Key Themes The show delves into several deep themes: Duality of human nature: Dexter is both a hero and an antihero. Morality and justice: The "Code of Harry" raises questions about the boundaries of justice. Family and relationships: Dexter's bond with Debra and his attempts to fit into society are central to the story. Reception The series received critical acclaim for its storytelling, Michael C. Hall’s performance, and its suspenseful plots. However, its original ending left fans divided. In 2021, a revival titled Dexter: New Blood was released to provide a fresh conclusion to the character’s story. #dexteredit
