That is my opinion of Disney movies. The ones that are not bold - I either don't like them or don't really remember them enough. I can easily say my favorites are Sword in the Stone, Lion King, Aladdin, Little Mermaid, Cinderella, Alice in Wonderland, and Fantasia. I mean, I really like a lot of Disney movies. But some are really bad.
But when it comes to Pixar vs. Dreamworks, Dreamworks doesn't hold a candle to Pixar when it comes to animation. And most of my favorites of those have come from Dreamworks.
Don Bluth made some damn good films and so did Miyazaki. I know people have mentioned them, but they are worth mentioning again.
