This movie and CSM's review of it were both disappointing to me. First, most of the jokes (references to evolving, opposable thumbs, David Bowie) were adult-oriented and there weren't enough little kid jokes to compensate. Second, my not-quite 5-year-old son who didn't even bat an eye watching Star Wars: A New Hope or The Goonies at home was TERRIFIED! He told me halfway through that it wasn't funny, he was scared, and he wanted to go home. My son does not scare easily, but I had to hold him in my lap for the last 30 minutes and talk him through it. He was very scared of the evil alien. Since this was only his third theater trip (the other two being Cars and WAL-E), I can only guess that scary scenes on the big screen were too much for him. It’s probably fine for most kids but if your child is young and sensitive or has little exposure to the big screen, you might wait until it’s on video.

This movie was actually not bad I like monkeys so it was a bit of a shock.

I think this was just bad, but I also think it should have been PG based on the scary scene in the cave. Don't see it, though, and then you don't have to worry.

The idea was great but the script was weak and the directing more so. What bothered me the most was the fact that "G rated" apparently no longer means appropriate for all ages. There were numerous adult jokes in the movie including the old "is that a banana in your pocket." Please DO NOT think that children do not understand these jokes. They have been exposed to this stuff since childhood (thanks to movies like this) and someone WILL explain it to them if they don't know already. Otherwise, this is not bad, but wait for DVD.
