Dexter (TV series)
Dexter is an American television crime drama mystery series that aired on Showtime from October 1, 2006, to September 22, 2013. Set in Miami, the series centers on Dexter Morgan (Michael C. Hall), a blood spatter pattern analyst for the fictional Miami Metro Police Department who also leads a secret life as a vigilante serial killer, hunting down murderers who have slipped through the cracks of the justice system. The show's first season was derived from the novel Darkly Dreaming Dexter (2004), the first of the Dexter series novels by Jeff Lindsay. It was adapted for television by screenwriter James Manos, Jr., who wrote the first episode. Subsequent seasons evolved independently of Lindsay's works.
In February 2008, reruns (edited down to a TV-14 rating) began to air on CBS, although the reruns on CBS ended after one run of the first season. The series has enjoyed mostly positive reviews throughout its run and popularity, including four straight Primetime Emmy nominations for Best Drama series in its first four seasons. Season 4 aired its season finale on December 13, 2009, to a record-breaking audience of 2.6 million viewers, making it the most-watched original series episode ever on Showtime at that time.
