If you will read the thing above about Jason being a "psychopath", that is actually a lie. He his a severely mentally-retarded kid who everyone made fun of in high school but they went too far and killed him. So his mother is and great grief and she uses some sort of spell that will bring her "now 40-year-old son" take revenge on anyone who dares lay a hand on the camp or deathplace of him. Excellent movie, some mild sex scenes,and a little bit of profanity. There is some what of a lot of violence if you get the unrated version but nothing that would be a "SAW 4", certainly any 13-year old boy would develop good companion skills and enjoy this. I know you would not want yourself too think a lonesome retarded guy is inappropriate for your kids.
