K-Cinema is definitely very very very good but unlike Japan South Korea doesn't have a long history of free expression and mass cultural consumption to earn the capital-G "Great" label, but I mean they're certainly making very fast progress towards it.
yeah I mean definitely the best c-cinema (HK era, alas) and j-cinema of the past is above k-cinema, but the stuff I'm aware of lately (again, I'm probably missing stuff everywhere) is definitely tilting K-ward. yeah, not sure if it's Great yet, but we're definitely getting some good stuff.
