In the United States, a movie rating system is used to inform people, particularly parents, on the content of movies so they can make informed decisions on what their children should watch. Such ratings are influenced by the movie's content including drugs, violence, and language. The ratings include G, PG, PG-13, R, and, NC-17. Personally, I think the ratings can give me a general idea on what might be appropriate for my kids, but each person's value system or tolerance for certain content can be influenced by personal background, religion, or family beliefs. In fact, there are some movies that are considered appropriate for teenagers that I find offensive, so the rating system might not be as useful.
So, what about in your countries? Are movies rated in any way to inform audiences of the content? If so, describe the system and then tell whether you think it is an effective method of protecting children from harmful material.
