Is it the characters or the actors you don't find attractive? I don't really find the actors all that physically attractive (I think they seem hella awesome and I would probably die from squee if I ever got to meet them, but I'm not really attracted to any of them), but the characters? Totally. It's all about the character personalities and their relationships with each other, plus the story used to be very interesting and captivating, and all of it kind of mixed together and made me love the show and the characters. *shrug*

But, yeah...why try to force yourself to watch it if you can't seem to get into it? Either you like something or you don't, and if you don't, I don't see the point in spending time and effort on it just because.
