I have to disagree with the rating this movie has been given. While it has a LOT of swearing, it's nothing that any teenager hasn't heard before, especially if they have older siblings. I myself have two older brothers and they swear just as much as the four brothers in this movie did. As for sexual content, you'd find more in a PG-13 movie. Violence.... it might be a little much for some people, but there's no more than you'd find in a typical 'bang, bang, shoot 'em up' movie. I actually found it to be a rather good story about four brothers out for revenge on those who killed their mother.
