I wonder if Squid Game has had an impact. Gi-Hun had a flashback to an auto factory strike that was pretty traumatic that led him down the path to sign his life away to the game. https://labornotes.org/blogs/2021/10/real-life-auto-strike-b...
So many of their recent films with worldwide acclaim are about rampant classism and economic inequality. Even as someone not super in touch with Korean social sentiment, I still get the feeling that Koreans are getting super fed up with their status quo. Might not be "having an effect" so much as "reflecting the way they feel".
Ultimately the movie industry in Korea is made of very wealthy people parading like friends of the poor. very amusing.
