Dexter

2006

Michael C. Hall plays Dexter Morgan, a Miami police blood-spatter analyst who is secretly a serial killer living by a code his adoptive father taught him: only kill murderers who escaped justice. Jennifer Carpenter plays his sister Debra, a detective who does not know. The Showtime series ran eight seasons from 2006 to 2013, with a finale that fans still argue about, and later spawned the revival New Blood and the prequel Original Sin. This entry is the original series.
