I went to see this straight from work having had a crap day, which meant I wasn't really in the right frame of mood to see a film. I enjoyed it in parts, but did find it dragging along in parts. It's cleverly done considering the lack of dialog in the film. The robots are strangely human, which is due to their faces. The spaceship that people live on made me think of A Brave New World.
On the whole, tho I wasn't that impressed with it. I didn't find it that funny compared to other animation films that I've seen and IMO some of the other offerings by Pixar are much better: Monsters Inc., Finding Nemo, The Incredible, Ratatouille.
