Frankly I could swing either way myself. Regarding story and animation, I'm not sure I could say one is more important than the other because they're supposed to compliment each other, like a person's personality traits making up his unique and cool originality.
For example I was watching that first show on Adult Swim that's animated (horribly) like that of Dr. Katz. Yeah the animation is terrible, but I think it adds much to the humor at times. It's really funny. So for a fan to say the show is bad simply because the animation is might not be a fair judgement, woud it?
Although to that specific show I'm somewhat biased because although I think it's really funny, something deep down says I'd rather have Dr. Katz back. I know, love, and miss the characters and the humor.
