Films aren't meant to be historical documentaries.
But for heaven's sake, another film about WW2 ? Its become a national obsession to retread the events of 1940, the plucky heroism of Dunkirk and how we stood alone to best the Nazis.
There's too many films glorifying war, especially WW2, when we should tell our children about the appalling human costs of WW2 and how future generations should never repeat the same mistakes.
In the meantime, Germany and Japan who were decimated by the war went about rebuilding their society and their industry and have achieved greater economic prosperity than we have.
