Battlestar Galactica (BSG) because it:
a) is not a sci-fi show with utopian aliens
b) politics (especially Iraq and religion)
c) hot women
d) space (especially the battles)
Futurama! That's counts as a sci-fi show, right? It also has sweet tech, like the smell-o-scope.
Ooh, and Chappelle's Show. That's a great tech show. The Haters is Time have a time machine, and then there was that episode where Chappelle visited the interwebs and punched out the spammer. That was awesome!
