Films like 1917 focus so much on style that they leave behind any narrative strength. 1917 plays like a Video Game, and would probably make a great 10/10 video game like Call of Duty. Now, from a cinema point of view, the cinematography, production design, and wardrobe comes together very strongly, you should probably wait h it for the "single shot" method employed. What doesn't come across at all is any sort of tension- any sense of true danger. Compare this with Birdman, where you actually feel emotion+tension despite the one continuous shot. The one-shot in his film is a gimmick a does not add anything. It is often distracting.
