It sounds as though tabuno's viewing situation for Dunkirk, which he judges so harshly. were far from ideal; in fact they were terrible. As for "experimental," great art is always challenging, when it is new. The more so the better. Much of what is exciting about Dunkirk is because it is innovative - and yet it has classic elements.

Dunkirk actually has many of the elements of a classic, epic war movie - fighter plane battles, for instance; excited discussions among those in command; the danger, the excitement, the terror of being attacked and taking flight.
