I just finished watching the entire 4 seasons on DVD which I have been watching since August 08 when my brother told me how good the show is. I can’t wait for tonight’s episode, but it will be different for me to watch it with commercials, and only one episode at a time. But I have to say, I haven’t seen a TV Series this good ever!
I would also recommend Dexter from Showtime. I don't watch much TV, but Lost and Dexter both get thumbs up from me.
