Just because it's about ponies means it's a bad show? That doesn't make much sense. Although the cutesy parts get a bit annoying at times, MLP:FIM exemplifies a good cartoon.
I thought it was bad at first, but simply watching the first episode changed my mind. It was nothing like a "perfect world plot" or a "toy commercial", it was great.
Go ahead and watch what you please, but posting rude messages (in a topic you shouldn't be in in the first place if you hate us so much) because of television viewing opinions isn't a very mature thing to do.
EDIT: Especially if you're trying to make your tastes look mature in the first place lol
