Same as above... though I don't think these are spoilers... in essence I don't think children will get 70% of the movie. At least there's pretty colors for them.
This is a very bold movie, with a lot of it meant to preach about the seriousness of our dependency on computers and machines... in essence losing our independence to these machines who do everything the same way every day, making everyone so comfortable they become blobs of humans oblivious to the world around them. It makes the humans look more like machines and vice versa, and while it still has quite a bit that kids liked in the theater, I don't think it's a "Finding Nemo" type movie catered to the attentions of children. The required repetition of the machines to show how everything is automated. The lack of dialogue that helps you notice all the other things about the robots and the world around them... a tirade on the duty of people to return home... I just don't think kids will get it, and I don't know if it should really be labeled as a kids film. I have to say good for Pixar for putting it out there though, it actually says something and isn't just another repackaging.
