From strictly action point of view the movie scores big but otherwise very ordinary movie. I still consider Saving Private Ryan as the best movie based on WW II. Dunkirk does not have any drama. Whatever human elements shown is at the superficial level. Very disappointed.If they had started and ended the movie based on some family drama then it would have scored big. Churchill's famous speech in the Parliament is read by one of the character from a news paper and does not have any effect. Instead if they had played the audio in background it would have had much greater effect.
