Showtime has supplied us with the poster for the upcoming second season of their cult favorite Dexter. Starring Michael C. Hall, the show chronicles a likable Miami police forensics expert who moonlights as a serial killer of criminals who he believes have escaped justice. It’s also pretty damn gory. Season 1 is being released today on DVD, so now’s your chance to catch up before the 2nd season premieres on September 30th.
