I HATE Family Guy. Like, unreasonably so. I find it so irritating, and like it's just a Simpsons knock off, filled with gags that have nothing to do with the story, and are there just to get quick, simple, cheap laughs, and they aren't even funny. It completely lacks creativity and originality.
South Park is okay. They have some funny episodes, and some that are kind of meh. Overall, I enjoy it, though.
