I used to like Garfield, but there was an episode where Odie gets thrown in the pound, and Garfield was a total jerk and acted like he could care less. I got really bent out of shape over that episode, especially when Odie is getting dragged away and Garlield is half-heartedly like "goodbye old friend" then just shrugs him off. I literally stopped reading the comic and watching the specials after that happened.
I'm also a sucker for the spider and the pig in Charlottes Web. I cry my eyes out every time I see that. The remake from a few years ago was really good too.
