I forgot to plug the nonprofit Common Sense Media— I frequently check this before watching movies with my fam so I can get a heads up on what themes to expect and gauge whether it would be appropriate for my kid at the moment. The site has rating systems that are pretty detailed: not only info about profanity, drug use, and violence, it also has ratings for representation, gender messages, and educational value. There’s even a “Talk to Your Kids” section that has discussion suggestions specific to that movie. The site isn’t specific to movies, either— it covers books, television, games, etc.
