This is not my usual sort of film, I watched it by chance.
Brittany Murphy plays an American adrift in Japan, and the film was clearly set in the real Japan, with real Japanese actors and much of the dialogue in Japanese. As a result it is constantly intriguing, but not exactly pacey. If you are patient it unfolds in a satisfying manner, never quite heading off into cliche or predictability.
The real strength is Brittany, who does well with a character who should be irritating, but actually manages to win you over without ever becoming trite or saccharine.
Having said all this, out of our family I was the only person who really liked the film, although everyone else was happy enough to stick with it. Probably a bit too real for teenage girls, this is only ever likely to appeal to a fairly niche audience, but if it is you cup of ramen, then it is entertaining and well put together.
