I too quit watching the new BSG halfway through the first season. I didn't care for a single one of the characters. If you can't "relate" to any of the characters in a story, it fails to really engage you.
I'll tell you a show I currently have a seething love/hate for and  that is Smallville!!! I love Superman, but this show insults me in just about every episode and yet I'm still watching the damn thing 9 seasons in!!! For some reason I just can't help myself. I keep waiting for Clark to become the hero he's supposed to be. I really want Dean Cain and Lois & Clark back!
