I took my kids to see this yesterday.
It's not a modern calssic like Toy Story, but it was very good.
There were very few "laugh out loud" moments, but there were a few good gags, one of which involving reference to corks and anal probes was done well enough to slide by my 5 year old, my 10 year old figured what the cork was for and the adults in the audience got the whole joke.
Overall it was a pretty good film and the kids and I enjoyed it.
