I REALLY didn't like Dunkirk! I know that I am in the minority, most people who I know, who saw it, really liked it.
Personally, I got lost watching the film, time warping back and forth, left me a bit confused, and too many of the characters/actors, looked too much the same, that I didn't always know who's story line I was following. I got anxious, during each of the near drowning scenes, but that is not enough to dislike a film. IMO it was terribly historically inaccurate.
There over 300 thousand on the beach looking to get evacuated, but in the film it appeared that there were only a hundred or so extras. They could have used cgi to create thousands.
There were what? 2, 3 navy ships? IIRC there were 39 large navy ships at the rescue including some destroyers, and 850 or so "little ships" private sea craft greater than 30 feet in length with relatively shallow draft.
There was no mention of the rear guard fighting of the French, who bought time for the allies to get off of the beach. The rear guard fighting has historically been compared to the Spartans at Thermopylae, yet there was no mention.
I really doubt that the men would have stood single file on the beach, for hours, and not dive for cover, or shoulder their rifles and take aim at the strifing german planes that were strifing the men on the beach.
Just terrible.
