A weird cinematic sub-genre has shown some staying power.
It’s part of a desensitizing process. Marginalizing the elderly - easier to euthanize by way of economic need.
I took your advise and watched the film version of "Snowpiercer". I don't watch horror. Thank you. I enjoyed it. I must tell you however that Toad and Glen Phillips are soft rock not in the folkie genre. Try a Martin Carthy or Anne Briggs record for that.
