I actually like just about everything Pixar does and I love plenty of animation.
the thing, is, what I call cartoons, are cheap worthless anime crap that pretends to be mature and discuss "deep issues," when all it really does is present cardboard one-dimensional characters, horrible low rent animation, and the concept of maturity never surpasses "boobs."
Yes, I've seen a handful of decent japanese anime--the Miyazaki films come to mind--though even those start off spectacularly, but by the third act collapse under their own weight as they have no idea how to finish. The narrative is lost, and the characters begin to start departing from their archs and do outlandish, uncharacteristic things for the sake of finishing under a reasonable running time.
So, I love plenty of animated films, I think it is a fine vehicle for story telling. I do use cartoons as a disparaging term, because there is a lot out there that is held out to be high-brow when it really is low-rent.
