I understand your feelings on going and seeing this movie. my brother in law I am positive will never see this movie because of the fact that it will give him flash backs when he goes to sleep at night. I don’t know what he did when he was in the army and only rarely has he ever talked about it. I do know that he has probably read the book but for him the visuals of any war movie is just to much for him. I wonder how many other veterans that is the case for.
The sounds of gunfire and explosions can also be "triggers" for many. If one must see it, best to view it in the privacy of one's home with one or two supportive friends around and no alcohol, etc.
