Out of these dramas that you're referring to, I watch Lost and Jericho. I think if I had the time to watch every past episode I'd watch 24 too, but that's too many episodes to watch and I can't just jump into a series. I always the first few episodes of any other "popular" new TV series so that I can make a somewhat fair judgment of them. Heros and Desperate Housewives haven't done it for me, and I'm still figuring our if I like Drive yet.

I watch a lot of TV drama's that don't fit your description too, especially the three L&O's, the original CSI and Numb3rs.

But the majority of my TV watching goes into a few comedies (My Name is Earl, The Office (US version) and Entourage) and cartoons (South Park, The Simpsons, Family Guy, American Dad, Aqua Teen, King of the Hill).
