The Great Happiness Space (2006)
It's a story about the hosts in Japan, men who work in bars that provide women with companionship. I'm not selling it well, but..it's really, really interesting. About the dynamics of people's need, the women seem really resolved to understand what they're doing at these clubs, except you wonder about the illusion that spending creates love.
I dunno, but it's an interesting experience in sadness.
