This is a list of what I would recommend for anyone trying to get a more wholesome idea of Korean film. This isn’t the most extensive list, but is maybe more diverse than what you will find “typically” (I tried to include documentaries, queer Korean cinema, women’s cinema, films from and on the Korean diaspora).
"Nevertheless, the fact is that there is nothing as dreamy and poetic, nothing as radical, subversive, and psychedelic, as mathematics. It is every bit as mind blowing as cosmology or physics… and allows more freedom of expression than poetry, art, or music… Mathematics is the purest of the arts, as well as the most misunderstood." - Paul Lockhart
