Fairy tale of the young guy with the head full of nice ideas trying to save the world. World of robots. Made by robots and used by robots.
Prepare for that everybody in this movie is a robot. Not only the humans, but also toys, toasters and toilets. And it’s nice, because everybody (and everything) behaves like in normal world. It’s again the same story — take something/somebody (bug, fish, toy, cars or for example fairy tale heroes) and let them live a normal life with all the absurd situations coming from the fact that it’s not human, but behaves the same in a very natural way.
You have probably seen some other movies (the best are surely those made by DreamWorks SKG and The Pixar Studios). This one is, by my opinion, not so good. But it is more than good enough to be seen in the IMAX theatres. And it is also funny enough for kids, even if it is not rated as clean as possible (MPAA PG for some brief language and suggestive humor). And I strongly recommend to watch out for the original (not dubbed) version.
