This touching and deeply thematic film went straight into my list of favourites.
First of all, the shoegazerish soundtrack does a great job of creating a dreamy, alien atmosphere. The film is essentially about two very different people who are both lost and lonely in the busy city of Tokyo. Lost in a strange culture, desperate for directions in life. The theme works on many levels and can be observed in many details. Main character Bob (Bill Murray) even has trouble interacting with the Japanese because he's almost twice their height!
This isn't just a clinical study of the human condition, though. As always, lost sheep find each other. And it's a pleasure watching their friendship unfold, very slowly, with long stares, melancholic silences and believably awkward dialogue. The ending maintains the tone of the film, without making concessions to traditional Hollywood norms.
