My sister kept insisting that I should check out the Showtime series Dexter. However, I didn't get around to watching any of it until this summer. It took a few episodes, but then I was hooked.
Michael C. Hall does an amazing job as a forensics blood spatter specialist who moonlights as a serial killer. He manages to make his character likable, funny and believable which is really the key to the succcess of this series. In general this series is very well acted and written and I love the fact that there are multiple story lines to follow.
Season 1 has been available on DVD ($22) and now Season 2 has just come out as well. Or, you can download individual episodes ($1.99) from either Amazon or iTunes. I'm not sure if this is available in all areas, but Comcast cable offers season 2 in their "On Demand" lineup. I'm still working through the season 2 episodes trying to drag them out until the next season starts.
The Season 3 premier is Sunday, September 28th at 9pm. The countdown begins!
