I took my 4 year old and he loved it. I'm not sure why the PG rating, perhaps some suspense/action at the end, but I don't remember anything that made me worry about Jamin. There is one kiss, but it's really cute and sweet. Here they showed a preview of the Christmas Carol and Jamin got scared during the preview, but he is pretty easily frightened (he won't even get near scary displays in the store at Halloween), so it may not bother other kids.
