Why do movies have to be rated and censored?

Movies have to be rated and censored to protect the audiences from inappropriate content and to respect cultural values and sensitivities. Movie ratings and censorship systems are designed to provide information to the public and parents about the suitability of movies for different age groups and to prevent the distribution of content that may be harmful, offensive or illegal.

The primary goal of movie ratings is to inform audiences about the content of movies, so they can make informed decisions about which movies to watch or avoid. Ratings systems vary by country, but they typically include G, PG, PG-13, R, and NC-17 ratings. The content that determines a movie's rating can range from violence, nudity, drug use, and profanity, among other factors.

Censorship is the process of removing or banning content deemed harmful or offensive from movies, books, or other media. Censorship can be controversial and is often criticized for violating freedom of speech. However, censorship is also essential to protecting cultural values and promoting social norms.
