All due respect to those movies (3 of them which appear to be documentaries) but they have not had the same cultural impact as a movie like Apocalypse Now had back in its time. It's a shame, I'd rather a director like Nolan had made a movie about Iraq or Afghanistan instead of Dunkirk, the same as Coppola had made Apocalypse Now just a couple of years after he had directed the first two Godfather movies. That way you'd be 100% certain that said film and its vision on the realities of current war would make it to almost all the cinemas around the world.
