I really liked Finding Nemo. I’m not sure how Pixar put out 5 quality films in a row. You can’t help but be impressed, especially compared to the complete and utter crap from Disney’s traditional animation studio.
I didn’t really like Shrek, and wasn’t crazy about Ice Age (and not because Blue Sky turned me down on a job interview), but somehow Pixar manages to write good stories, refrain from milking sequels (only one so far), and make their movies look even better each time around. I thought Monster’s Inc. looked incredible, but visually, Nemo beats the snot out of anything done before.
