on the topic of dunkirk the movie... Though of course the point of view is from the british, you see the french defending the perimeter (in may 27 16 british battalions were defending it), and most of the time france is mentioned it isnt in comments joking about them or anything. And to compare for Saving Private Ryan or Band of Brothers, the fall of france is probably the easiest moment to pick on the french and say something. You could have the brits complaining about gamelin, the french soldiers, the german breakthrough in the french sector in the ardennes and what not. None of that was in the film and its good that it wasnt.
But Spielberg and co sure whenever the brits show up or are talked about in their ww2 films its always in a joking way about the war effort. Even when Omaha beach has just ended, and while everyone in both the british and american armies are much more grounded in their expectations and are still thinking about omaha... there has to be a comment about caen not being captured on day 1 and montgomery being overrated (which is so much out of place that is hilarious really), even though pretty much the only important day 1 objective that was captured was bayeux by the brits and the all the beaches werent even connected, so no one at the time didnt even think upon caen when the chance was missed. But post war historiography sure makes its way to the characters in the film through the (completely anglophobe) historical advisor to the film.
Or when band of brothers they receive the news in market garden they are being commanded by the british and all go anal.... well someone forgot to mention them that Montgomery was also commanding them in normandy overall so that is a delayed complaint i guess. Something the advisor also forgot about.
The french should be happy of how they were portrayed in Dunkirk.
I guess the conclusion we must make is that its the americans that like to push down their allies in pretty much all occasions, including in films. The patriot, we were heroes, U 571 which is hilarious, Saving private ryan and band of brothers... and etc. I mean people think d day was an american led thing but the brits had WAY more ships, more planes and more soldiers, and actual command in all 3 branches. But yeah.
