Frankly, it isn't that good a movie to warrant all the attention it is getting. Chris Kyle was no more of a hero sniping from a rooftop than were the guys who were kicking in doors to search for terrorists. Like many others he came home with PTSD, but volunteering for four tours didn't help that condition or his family life, either. For me, the main lesson of the movie is that we squandered the sacrifices of these soldiers to make Iraq safe for its citizens.
