Took my 7 year old daughter, she was able to follow it and really get into the story! The "adult" themes were really downplayed and there were none of the usuall inuendos that are all to common in kid movies these days.
Gave it a Go instead of Must Go because I am an action/sci-fy guy and this would not have been my first choice, but it was very entertaining and I am glad I saw it.
