WHY do we have ti watch movies about losers?

Rating: 1/10 (27 July 2015)

NO spoilers here. Alright, a mother's boy gets stressed out over a bit of the WAR ACTION, and everyone all of a sudden treats him like they owe something to his parents?! Patiently every veteran lets this momma's sweet boy deal with his/her childish stresses while everyone gets killed because of this boy's lack of pretty much everything? WHAT WAS THAT? A guy who refuses to fight a mortal enemy is worse then the enemy.
So, what is this movie about? Is it about a hypothetical situation where and when you get this strange right to do or not to do whatever, including the direct orders from your superior officer, and everyone keep doing their pointless best to make a soldier out of you? I could not finish watching this, despite the fact that I can definitely appreciate a good war movie. What would make us want to learn anything from this?
