Dexter is one of the most interesting shows in cable television and it's addictive. I didn't really know about Dexter because I didn't have cable, but someone at work spoke very highly of the show. One day, I was browsing my Netflix account and noticed that it was available for instant viewing. I saw one episode and was addicted. I finished season two, then caught up on the first season and now eagerly waiting for season 3. I'm now a subscriber of Showtime, only for Dexter.
