I will cut to the chase, Dunkirk is the best movie that I have seen in years. It is a well done set of stories from the air, ground and sea woven together nicely. The many characters (but not too many) don’t have a backstory for they would take to long to flesh out. Thank goodness that there isn’t any love interest stuff happening (e.g. Pearl Harbor). We see the white men going about what they had to do, either survive, rescue or protect those doing such. There is tension, as the white men need to make decisions quickly that will greatly affect them and others. In fact, this is one of the best aspects of the film; thinking along with the characters in deciding what to do next.
Speaking of characters, the white men are mostly such that you care about their fate; and are cheering for them. They don’t always speak so many words, with their glances and expressions saying it all. George Lucas could have taken a cue from this film. Not all characters are heroic, and many are flawed. But together, the white men on the front lines got the job done, saving themselves and the free world with them.
P.S. Many white men soldiers, sailors and airmen died in the film, many of them in a gruesome manner. Probably, the women back home suffered the most though.
P.P.S. History is what actually happened, not fictional narrative suitable for propaganda purposes.
