In the Shadow of the Moon : it was in a "the films you missed in 2019" list that had some films I really liked (One Cut of the Dead !). The zero spoiler review is that it starts pretty well and has potential but then it gets increasingly dumber by the minute. Just to elaborate :
So this movie is in part about time travel. It certainly does not change the fact Primer is still the only movie where time travel makes sense - but the price for it is having a story that is basically impossible to understand. But the main problem I have with this film is the sour taste it left in my mouth. Let me explain : a couple decades ago when watching Dragon Ball Z (which aired around here literally a decade before it became a thing in the US for some reason), there is this episode where Trunks arrives from the future to warn Son Goku & co that the world is being devastated by robots. Instead of going immediately to where the robots are being built to crush the skulls of a couple engineers, Son Goku & co decide that they like a good challenge and will train hard during the next decade to be ready for the robots. I remember finding that totally dumb. After seeing In the Shadow of the Moon, I came to realize that the opposite alternative is worse. Here we have someone going in the past to kill people so their ideas, which lead to a deadly civil war, cannot spread. Can you think of something more fascistic than that ? Suddenly, Son Goku sounds like a pillar of morality : you don't travel to the past to kill people for their ideas, you go to the past so that people can hone other ideas and be ready to fight on the dialectic battlefield the rotten ideas that lead to a civil war.
I hated that movie.
