tv show

I don't watch a lot of tv but it seems like there's a lot of good tv show on the air. I watch one tv show and it's "24". This show is so addictive that I don't want to start another addiction ;-) But from time to time when I open the tv and change the channel I can see that there's some good stuff going on. With "24" who is almost finish for the season... do you have a tv show to suggest ? House, the Office, Lost... Any suggestion?
