The director and studio behind the documentary “Bully” won their battle to have the movie’s rating lowered from the restricted R-rating down to PG-13. Even though it doesn’t have any explicit sex scenes or extreme violence, “Bully” was deemed more risqué than “The Hunger Games,” a film about kids killing kids.  Ethan Noble  is the chairman of Motion Picture Consulting.
