I thought the movie was well done. We all had a good time watching it. Very entertaining. My kids were laughing. I was laughing. I think the PG rating was appropriate. To me, G movies are geared to children. PG movies are geared to everyone, so light language (occasional hell or damn) is to be expected. The adult humor was presented in such a way that it goes over the head of children.
Having said that.. I will caution that there is one instance near the end where the villian uses the word 'hell' with such intensity that it really stands out.
