About the movie...
Recently I've been watching Korean movies that more or less portray Korean life realistically and I think this is very much one of those films (within a certain context). More importantly... I think while there's much to appreciate in the film for non-Koreans, the much more subtle points in the movie quite frankly can only be understood by Koreans.
But... Having just said that, and having just watched this film I think I can easily say this is one of my favorite movies ever.
