The story of Dunkirk was an extraordinary historical moment. This movie tells it from a very broad viewpoint, attempting to cover a lot of ground, but no one movie will ever be able to capture fully the scope and gravity of that event. It is well worth watching to get a glimpse of the horror and anguish experienced by those many thousands of soldiers, and the astonishing effort of the few RAF they could spare and the civilian flotilla that enabled them to get back home, away from certain death or capture by the Germans. This movie captures a sense of the scope and desperation of an almost incomprehensible moment in history, but can any movie ever capture such a reality? But that's all we'll ever get, just a glimpse, no matter the story teller. Watch it.
