1917 feels like what Scorsese really meant when he described the growing the cinema experience becoming a theme park ride. It's not a bad thing, and it's not even necessarily not 'cinema'. 1917 is an experience film. It doesn't aim for any transformative artistic statement, but rather a technical masterclass, with loose concepts of the audience having their perspective shifted in this new angle.
It is a brilliant creative decision, with some amazing (if a little surface level) technical mastery. It reminds me of Gravity. Something you've got to try and see on a bigger screen.
