PG is now a worthless rating http://www.forbes.com/sites/scottmendelson/2013/11/26/disneys-frozen-proves-worthlessness-of-pg-rating/ http://www.forbes.com/sites/scottmendelson/2013/11/26/disney... The difference between PG-13 and R in many cases is completely arbitrary. The ratings lump many kinds of movies together and says absolutely nothing about their content. No movie can be NC-17 or unrated because that is a kiss of death. No theaters will play it, no big box stores will sell it. I think what R can get away with has broadened considerably because of that.
