I agree with you on 24!!! I love that show!! I've bought every season on DVD. You need to watch this past season, it's one of the best seasons. Just an FYI, in case you didn't know, next season is the last one unfortunately.

I liked Prison Break, but hated the ending.

No LOST? You have to watch that.

And you definitely need to add True Blood to your list. Bilbo posted links to the 1st season (there's only 12 episodes), in our thread about the 2nd season. You should give it a try.
