We took our kids to see Night at the Museum the other night. We wondered about taking the younger ones (7 &5) but decided they could go.
We all enjoyed it. It's a fun movie. There's not a lot thoughtful about it, although there is some, and as my husband says, you could drive a truck through some of the holes, but overall, it was fun. It was quite clean - the "occasional rude humour" was really only one incident and it wasn't that bad.
The message of the movie itself centers around the main character learning to stick to a job, even when it is tough. He learns that he can be a leader even when he doesn't feel like a leader. There was even some history - Teddy Roosevelt is one of the main personages in the museum and we learn something about his life through their interaction.
Movie Mistake? My husband spotted an overhead boom microphone in one scene. I missed it. We'll have to check moviemistakes.com and see what else we missed.
