Motion picture rating systems

Motion picture rating systems are issued to give moviegoers an idea of the suitability of a movie for children and/or adults in terms of issues such as sex, violence and profanity. In some jurisdictions, they may impose legal obligations of refusing the entrance of children or minors to certain movies; in others, while there is no legal obligation to do so strictly speaking, movie theaters enforce the restrictions. Ratings are often given in lieu of censorship.
