Probably the most gratifying and amusing show I've ever seen. I've never once finished a series from beginning to end besides Pushing Daisies (no, not even The Office, Lost, Heroes, Chuck, and everything else cause somewhere along the show I lose interest..) but something about Dexter kept me watching until the end of season 4 and all of it within a span of 2 months. I'll be waiting for season 5 to air this year soon. Can't wait!
