No, the movie isn't a constant spew of expletives. Those uttered definitely fit the context of the action. As for the violence........it's exactly as the book depicted it. It's bloody, graphic and realistic. Bodies are blow apart, blood squirts, RPG's impale without exploding. Considering the true violence of the actual situation, I think they curbed themselves rather remarkably. I don't know if I'd take a 13 year old to see it or not.
