Premieres: Sunday, June 30 on Showtime
Why we're watching: It's the final season of Showtime's serial killer drama, but as if that weren't enough, Season 7 left off with an incredible cliffhanger -- Debra knows all about Dexter and shot LaGuerta to protect him. We are dying to find out how the show (ahem) wraps things up.
