But what about the movies? I had a bad experience taking a kid to a movie theater once. I was living in Walla Walla and the kid was 6 or so. His parents failed to mention he had only seen animated movies and this one was live action (The Indian In the Cupboard). Kid lasted about 4 minutes before asking to leave. He was completely freaked out.
So, if you've seen WallE, please tell me what you think about attempting it with a 3 year old.
