[bong joon-ho festival]
The only Bong film I've seen is the brilliant Barking Dogs Never Bite, a richly textured dark comedy that captures contemporary Korean life better than anything else I've seen or read.
From what I hear, though, his subsequent films, Memories of Murder and The Host, are supposed to be great as well. The Korea Society has more information on the films.
Check it out if you have the chance!
