Movie ratings are a system used to classify films based on their content, helping viewers decide if a movie is appropriate for them or their children. Ratings are typically assigned by organizations like the Motion Picture Association (MPA) in the United States, which uses categories such as G (General Audience), PG (Parental Guidance), PG-13 (Parents Strongly Cautioned), R (Restricted), and NC-17 (Adults Only). These ratings consider factors like language, violence, sexual content, and drug use. They aim to provide guidance to parents and viewers, ensuring that audiences can make informed choices about the films they watch. Different countries have their own rating systems, such as the British Board of Film Classification (BBFC) in the UK, which uses similar categories.
