The real question is how old is your son. I have a 10 year old who I let see the movie and he was fine with it. I would not let my 7 year old little girl see it. She is too sensitive. It all depends on your child and how you think they can take a PG13 movie. You know your child. If your child saw Daredevil, the Hulk, or the last Spiderman movie and was OK afterwards, he will probably be OK with this installment of Starwars.
I think Star Wars was much tamer than the movies you described. Plus there's no cussing in Star Wars or other adult dialogue in Star Wars.
