John, you hit the nail on the head. I don't write, produce, or act. I do, however, pay good money to go see a film. While I have more than a nodding knowledge of history and military, I go to movies for ENTERTAINMENT! To often the movie industry forgets that it is an entertainment industry. A good film that is not realistic, bothers me in INSIGNIFICANT ways, I'm still entertained. And, yes I'm one of the ones who constantly makes comments on this and that (ask my long suffering wife!) not being accurate. A realistic film that is not any good is just a waste of my time - even worse, painful to sit through because now good history gets a bad and boring rep.
Keep the STORY good and the action moving. (Did anybody really care that the flying wing in the Indiana Jones picture was just a prop man's dream?). If the acting is passable, the movie will be just as good as the story.
One can make a good war film and not have it realistic.
Or, one could make a realistic war film and not have it good.
