For/Against MPAA

I am for the MPAA rating system, but i believe that there are some things about it that need to be changed. The rating system is very useful because it helps parents determine whether or not they should allow their kids to watch certain movies by the ratings that the movie is given. Its ratings are based on the contents and plot of the film. The thing that I don't like about the rating system is that it gives the MPAA too much power. Although it is not mandatory to submit your film for rating, most films that aren't rated don't make anywhere near as much money as they could have.
