"This following are the top 10 children's films that would even disturb adults, and none of them have a rating higher than PG. Although the MPAA rating scale judges films based on such categories as violence, language, substance abuse, nudity, and sexual content, it has a blind spot when it comes to "the disturbing," an admittedly broad aesthetic category.
The films below don't necessarily undermine the sanctity and reliability of the current film rating rubric, but they should help us remember that even the most innocuous-seeming films for the most innocent audiences can pack quite the thematic punch."
