Unlike some, I give most Americans credit for understanding that war is not pretty, and that our soldiers are not saints. Stuff happens, as is oft said, and our troops do what must and needs to be done to secure victory. It's war, the rules of engagement are...flexible. The most important thing is not to get your a** blown off.
Therefore, most of us feel we really don't need another Hollywood homage to the depravity of the American soldier and the nobility of our enemy. We don't need another trumped up piece of garbage the other side views as useful propaganda for THEIR "cause". We need more unabashedly pro-american films that rightly portray our soldiers as heroic, without hemming and hawing via liberal-esque moral equivalence nonsense.
We know our servicemen are not perfect, and we don't need Hollywood constantly reminding us of our/their falabilities. The American military is the best trained, most professional in the world, and that story needs to be told. For every single act of "wrongdoing" by our military, there are 100000 acts of "rightdoing". If this movie focuses on the norm rather than the exception it will be warmly embraced by the movie going audience.
