Because it's incredibly stupid, has no continuity, all the characters we're supposed to like act like jackasses, every episode has a stupid moral that makes no sense and is taught offensively, everyone is a flat stereotype, the jokes aren't funny, the actors are too bad to pull off drama, and the song choices are like bad karaoke versions that don't have any relevance to the plot at all.
And I say all this as a fan of the show. I watch it purely because it's so terrible it's hilarious, sort of like why I love playing FFX-2 so much or watching The Happening. Some things are just too stupid to hate. But, yeah, people who actually take this show seriously are a mystery to me. :/
