So long as the acting isn’t terrible, or the plot awful, even a mediocre film set during the Second World War is going to do well with an American audience. We love that shit — dead Nazis, all-American heroes, massive battles, and, most importantly, a major victory for the United States. In the coming months, we’ll see four more additions to this genre: “Hacksaw Ridge,” “Allied,” “Dunkirk,” and “USS Indianapolis: Men of Courage.”
