Wait, the one review is wrong.
The one review listed for this movie is wrong. It claims that the movie is PG for "frightening scenes, brief sensuality and language". Many sources (including the DVD cover and the IMDB itself) lists this film as being G-rated.
I just watched the movie and, despite the violence (most of which was comical and didn't result in the on-screen deaths of any characters, though there were two off-screen deaths and it's suggested later that perhaps they didn't actually die), I would definately say that it's G-rated. I don't know what movie the reviewer saw, but I don't remember any sensuality or language, and frightening scenes...maybe.
