Gabby started a thread where she said she did finally see it and was surprised.
For those that haven't seen it for the 'violence' reason, let me reassure you there really isn't much 'blood and guts,' it's much more of a thinking person's movie-the violence is more implied. This is not "Glory" which is an awesome movie, but very violent. In "Glory" there are shots of heads exploding and much of the very real trauma inflicted during the Civil War, including close ups of the primitive medical facilities and talents available.
Yes, in "American Sniper" men, women, and children are victims of war, but there's no gratuitous violence, mostly the violence is shown through a scope of the target, actions that make the shot necessary, and then you hear the shot, but not the carnage for the most part. Truth is, that's basically the way that Eastwood directs and it's also how Kyle wrote the book.
