This is not the best of movies, but I rank it high because it did it for me. Though the characters are not really presented to the viewer, they are developed through the movie by showing their actions. The plot is not really important here, and people that cling to whatever feminist or political agendas when discussing a movie are wasting everybody's time. It reminds me of an old Italian movie, I can't remember the name or actors because I've seen it when I was a kid, with a mafia boss that falls in love with a woman, kidnaps her but wants to charms her, rather that rape her. This is also about a generally violent man who's attention is captured by a beautiful girl and he also wants access to her soul, rather than her body.
The movie is full of contrasts and paradoxes, but what sets it apart is the atmosphere (I had my heart pumping a good part of the movie, without it being an action movie or anything) and the subtle way it reveals the deep needs of every character.
Its bad part, though, is that close to the end you keep expecting the movie to end and it doesn't. The slow pace of the movie doesn't help either, so a feeling of "is it over yet?" can easily set in.
I liked it, I recommend it to people who have the mood to see a psychological Asian movie about gangsters, prostitutes and the power of love.
