Finally watched the movie on Netflix, and I'll just say it's giving me a new appreciation for the show, which is approximately a bazillion times better. The movie is like an extra-dystopian Brazil without the humor, more unrelentingly dark than anything (and I have a pretty high tolerance for dystopias). The ending? Meh.
Kept thinking how glad I was to have seen Parasite before I saw the Snowpiercer movie or I would have been deeply suspicious of Bong Joon-ho's work in general, b/c Parasite is a work of genius. But if it took Snowpiercer for him to work out some initial ideas about class discrimination so that he could get to Parasite, I'm okay with that 😉
The show is much more effective, I think, in showing us the train and the various people and systems that keep the "pax Snowpiercer." It seems quite possible there was never meant to be room for all that in the story the movie wanted to tell, and that’s fine. I will admit that it was the general premise that got me to try the show, so it's all good, man ☺
