I think Lost is the only show that I've ever really cared about to the extent that I'll look through the message boards and stuff. I love that show and even though it's still fairly new, I have to say it's my fave of all time.
ETA: Arrested Development. I am hooked. I really really really hope another network pics it up.
I know its pretty common, but I absolutely LOVE Sex in the City. I own the whole series and I watch the dvds all the time. It probably has to do with my obssession with NYC and fashion, but it is so darn well written.
Lost and Battlestar Galactica! Those are the two shoes I read about on message boards and obsessively look forward to. *hides the Battlestar computer wallpaper*
NOW, I say Lost and I can't remember liking any show as much.
Some time ago, it would have been SATC before the Aidan relationship, because I thought the show went downhill after that. Six Feet Under first two seasons, and The L Word, first two seasons.
Before that I would have said Seinfeld.
