This film does no justice to those, like my father, who survived the horror of Dunkirk. The scenes on the beach are thin. There were many more troops and the beaches were packed, the aerial attacks were far worse than shown. The number of German aircraft shot down by rifle fire, which was important, is not shown at all. The destruction of the town and the bravery of the troops defending it is not shown either. Maybe I expect too much of a documentary and not so much Hollywood filming. But scenes of people drowning and struggling to get to the surface probably do not depict the true horror of the situation. This film is not worthy of the name "Dunkirk".
