1917 could be set in any war because it's not about anything. Not everything has to be about something, of course, but 1917 appears to be studiously about nothing. What it is, though, is awesome! Just really awesome! Like, holy shit, is it cool. There's not a minute, I don't think, where I wasn't trying to figure out where the hidden edits were and how they set up specific shots. I thought about it a lot and, God, the moment in the rain of cherry blossoms after that trip down the waterfall? PHEW! Right? You guys, it's so fucking cool. It's probably CGI, but what if it isn't? What if there were people in the trees with buckets of petals, waiting to get the timing right?
