I really liked this movie. I can't quite figure out why, however. It's not quite the psychological thrill that it was perhaps intended to be (we never really get into the head of Martin, a man obsessed with his old love, which most people think is what the film is supposed to be about), and the relationship between Helen and Honda never really becomes a focal point, but like City of Lost Children, it gains a lot of points by simply being a unique viewing experience.
The relationship that Honda has with Smokey (his sister) and Helen are realistic and almost heart warming. It would have been a more enjoyable movie if it simply focused on the trio, but the movie is very intelligent and thought provoking as it is.
