Great post! The amount of good cinema that is made in South Korea is impressive, and I am even pleased to see how some directors have ventured to collaborate with Hollywood without losing their style, like Chan-Wook Park with "Stoker" or Bong Joon-ho with "Snowpiercer".
I personally recommend "the wailing" a horror / suspense movie that blew my head, is from the fantastic director "Na Hong Jin" author of other great movies, check his filmography!
There is so much cinema out there that we have to see! It's a shame life is so short.
You make some excellent points, I completely forgot about Stoker (as I was a bit disappointed with it). 'Wailing' has been on my watch list for months, every day I hear great things about it and I am so excited to watch it! I am a big horror fan as well, and I appreciate these SK directors being unafraid to blend the thriller and horror genre so well.
