Starts off a little confusingly with a woman who has two different names, and lives in two different towns at the same time and writes letters to herself. Soon it makes sense. This has one of the best onscreen kisses I've seen in a while, but the kissing guy turns out to be such a patronizing douchebag I couldn't allow him in my life for another second. The girl was too meek, and I don't like these Japanese movies where women put up with douchebags for no reason. I'm surprised at how manipulative and icky the film is. The music sucks. I thought Shunji Iwai was one of the sensitive, enlightened urban male types. Punt.
