Yes, this is the point I was trying to make in my Post 53, that Hollywood gets too one-dimensional, too caught up in the immediate, personal motivations, ignoring the "big picture," which is a real part of a soldier's motivation - in any war. Thanks for expanding on the point, I agree completely.
I still want to see this movie, and hope it is a good one. I think it is possible for Hollywood to take that narrow approach and still succeed in presenting a respectful treatment of the story.
It's worth it if for no other reason than the scene where they finally get the flag up and the entire fleet begins blaring its horns and ringing its bells.
