Dexter to Kill Again... and Again

No matter how you slice it, this has been a disappointing season of Dexter from a creative standpoint. Only one-quarter of our poll participants believe it's on par with past years.

But the ratings remain strong and Showtime announced today that the Michael C. Hall-anchored series would return for seasons seven and eight.

"Dexter's enormous success is a real tribute to the great achievements of its cast, producers, and the powerhouse performance of Michael C. Hall,” said David Nevins, President of Entertainment, Showtime Networks Inc. “The series is bigger than it’s ever been in its sixth season, both in terms of audience and its impact on the cultural landscape. Together with Michael, the creative team on the show has a very clear sense of where they intend to take the show over the next two seasons and, as a huge fan, I’m excited to watch the story of Dexter Morgan play out.”

Added the show's star and multiple time Emmy nominee:

"On behalf of the entire Dexter family, we relish the invitation to delve ever deeper into Dexter's world."
