P and I saw this last week. I actually didn't fall asleep, which is a first for me since I always fall asleep during a movie at home and in the theater. It's really cute and has a great message for kids and grown ups.
WALL-E reminds me a lot of Perry. Who would be content in this world to build towers out of garbage and collect random objects. WALL-E is also afraid of unpredictable loud noises.
