I really did enjoy every minute of the film. I think the filmmaker was trying to recreate that feeling, that very peculiar feeling, of being in a busy place, things happening all around you, but being isolated, the only one on the outside. I got a few jokes that others didn't, too, since I understood the Japanese. The film triggered a lot of memories for me. I was very much "in the now" for the whole film. The film is not about a story so much as about a feeling, an experience.
