This is a movie that needs to be watched twice just to catch everything. The plot is non-linear and that will probably throw many people, especially those who are used to domestic movies with their spoon-fed plots. You need to pay attention to what's going on and allow yourself to be thrown around by the movie. I love this kind of movie that plays with time/space, but in a manageable way.

The Japanese really have a good firm hold on how to do this and do it right, with good pacing, a really darkly funny story, and plenty of surprises. It reminded me a lot of the anime series "Baccano", with its love of having a single story being told by different points of few at the same time, and times future and past often overlapping one another. It's a smart movie and I love smart movies and it is a shame that too often smart movies are hard to come by.
