he age system is straightforward. It utilizes letters that represent the age groups a film is deemed suitable for. From child oriented to adult restricted their system spans the spectrum from G, PG, PG-13, R, and finally to NC-17. One of these grades is given to every movie that the major production companies put out. Directors, producers, and writers typically have a target rating that they are aiming for, as the companies know that PG-13 movies net the largest sums of money. Along with the grades, the MPAA also issues a contextual warning about the potentially disturbing subject material. These warnings are intended to inform parents why a film received the rating that it did. For example: if the film was rated PG-13 for violent action; that differs from a film that is rated PG-13 for adult situations. A parent can then make a more educated decision on which films to allow their children to see.

I think there should be more enlightenment on meaning of all these rating figures for the man/woman who isn't in the field.
