Many jokes are multilevel and can be appreciated by parents whose children may not get the references. These jokes go right over the heads of the children. The only complaint I had, was that there were far too many product placements once they landed on Earth - 7-11 stores, pop chips, etc. I would also recommend that you NOT see this in 3D unless you really feel like spending a few extra bucks. There were very few scenes that even used 3D and those were more of the contrived sort (a paddleball where the ball keeps coming right at you). We took our glasses off and did not need them shortly after the movie started.
We took two kids with us to see this movie. One is 8 and one is 14. Both of them were very lukewarm about the movie. They both give it 2 stars out of 5. I am not sure who this movie is aimed towards. We did bring anyone in the under 8 category, so maybe that is the target age. Leave me a comment if you go to see it, I would love to know what you think of it!
