Yes, all movies receive a classification but these ratings do not tell the whole story.
Kids-in-Mind is a great website/app that answers all your questions and provides detailed information about every movie. Movie reviews are based 0-10 scale for Sex & Nudity, Violence & Gore, and Profanity. It also provides information about every instance of these elements to give you a complete coverage of these negative aspects of each movie.
Instances of substance abuse and a list of discussion topics generated from the movie are also included plus the message that the movie conveys.
This comprehensive information about each movie certainly helps your movie choice but remember... the final decision on a movie's suitability for your kids and family is up to you.
