The R rating says Restricted Under 17 Unless Accompanied by a guardian. This film is not appropriate for children. I'm sorry, it's just not. They won't like it (unless they're terribly mature for their age) and there's just too much foulness and intensity on display for them to handle. It wasn't made for kids, so don't bother trying to decide whether or not to show them this film. Just don't. It's rated R for a reason. I like this movie a lot, but would never recommend it or try to rationalize how the content in it isn't "that bad" so I can show it to my kids. Stop comparing this to Apocolypto and Saving Private Ryan and just admit that kids shouldn't be exposed to this kind of violence!
