The Korean filmmakers certainly has a certain point of view and they often incorporate horror to make points about their society. Certainly the epitome of this movement was the great film Parasite of 2019 (the last time I was in a movie theatre.) Now there is equivalent of this riveting movie in the streaming series on Netflix, Squid Game. I'm not going to say anything about the plot except to say the less you know the better. Watch it soon because someone you know is anxious to spoil the plot-point for you.
