a warning, this may contain spoilers~!
I just saw Bable the other day, and as a whole i liked it. I didn't think the stories related enough, the ties weren't very strong. Have you seen Crash? Those stories tied in well!
I loved the story about the Japanese girl, I've never been to Japan, so have no idea if that's what the teen culture is like. But I do want to eat at the 'Jpop'
Oh, and i think i missed the part when they explained what was on the note the Japanese girl wrote to the detective guy... or was it a note telling him that she was going to suicide?
