While it shows lots of violence, nothing was done to glorify shooting of anyone other than the bad guys and depicted Kyle's difficulty in taking out a woman and child who posed deadly threats to Americans in Iraq attempting to bring some kind of order to that country.
Kyle was shown as not terribly able to reconnect with his wife during his times at home but as it was told from his own words (presumably as I have yet to read his book), it neither makes him out to be anything other than who he was - a guy who loved his country, his family and his fellow soldiers.
He saw what he did as a job that needed doing and he just so happened to be very good at it.
He wasn't lying around looking to take out women and children in a foreign country but rather protecting his men while they did a job that we as Americans called upon them to do, i.e. rid the world of a bunch of people bent on using WMD against other countries, whom they hate merely for not following the brand of evil they follow.
That and some other nonsense which is very offensive to me as well as the other stuff Hollywierd includes to encourage adolescent males (of every age) to see the movie.
Most "stuff" complained about here occurs in the early minutes, so if one can get beyond that and the F-bombs constantly used, as well as being able to distinguish movie-killing from real life, it's a story that deserves to be seen, but be forewarned this movie has an "R" rating for a reason.
This is not a "woman's movie" which I never would see anyway but just to let the ladies on FR know that if you don't mind the bad guys being sent to join their 72 Virgins or even the good guys sometimes dying but no real gratuitous shots, just the facts of war as shown, see the movie.
Lots more gore seen in "Saving Private Ryan," so if you handled that OK, see this movie.
