One of the bigger ones that make ROTS inappropriate is the death of children. I don’t know if any edits cut Anakin drawing a lightsaber on kids as well as a few hologram shots and Bail Organa watching a kid get shot to death. IMO TFA is completely fine is not more appropriate than ANH, I’ve seen it three times and the only thing I can think if is Finn saying “Hell” twice in the movie.
Then how did TFA get a pg-13 rating? Han’s Death? Did the Motion Picture guidelines change over the years?
Welcome to 2016, where R rated movies are PG-13 and E rated movies are also PG-13. ALL MOVIES WILL BE PG-13! THAT IS THE WILL OF DARTH RATINGUS! MUHAHAHAHAHAHAHAHAHA!
