I like them both, depending on my mood. Though the sweet ones have the bonus that I can share with my teenaged daughter--if I feel like sharing, that is ;)
I think I watch even less TV than you do, but I have to second Buffy, Charmed, and Firefly--though I haven't seen any of them in quite a while. My 14 yr old recently discovered Buffy, and breaks into song at random moments, singing from the musical episode (hopefully you've already seen it? One of my faves...)
Thanks for the contest! Reading I do somehow always find time for ;)
