Ugh.
Ratatouille was the first Pixar movie I saw that was an utter disappointment (no, I haven't seen them all, but I've seen a fair number of them). It was so far from "feel-good" cartoon flick for me. Much more "I'll never get that two hours of my life back" movie. Not sure how close to two hours it actually was, but it felt like about 10 hours.
Not sure what they were smoking when they made that one. I realize that tastes in movies vary widely, but I still find it hard to believe that people actually like that movie.
To each his own, I guess.
