Interesting--we clearly react in completely different ways! I fall in love with atmosphere, particularly if it's at all dark and/or brooding. Hence, Angel, hence Carnivale, hence Galactica. Character-love comes later, if at all, and is normally not in isolation. For instance I don't find Six herself fascinating, but I do find the interplay between her and Baltar fascinating (disclaimer: I'm up to 1x03).

Man, I sound like a goth. Oops.
