If you have ever taken your children to a movie only to discover that the PG rating was was too much for your child, then Kids in Mind.com is the place for you. According to their website:
We enable adults to determine whether a movie is appropriate for them or their children, according to their own criteria. Unlike the MPAA we do not assign an inscrutable rating based on age, but 3 objective ratings for SEX/NUDITY, VIOLENCE/GORE & PROFANITY on a scale of 0 to 10. We also explain in detail why a film rates high or low in a specific category, and we include instances of SUBSTANCE USE, a list of DISCUSSION TOPICS that may elicit questions from kids and MESSAGES the film conveys.
It is a great place to see what is really going to be shown on the screen so you can prepare yourself or just skip it all together.
