More than the writing, I hate the art of this show. Look at it. It's fucking hideous.
Just look at it:
I cannot be the only person who thinks that art is shitty. And that's not even the worst in the show.
But I hate the show on principle, too. Any American show that tries to include anime-esque art just to be popular (Kappa Mikey) instead of being influenced by it (Avatar: The Last Airbender) is a steaming pile of shit. Plus, I think Japanese people who watch the show might actually be offended, instead of amused.
