Satisfying but spotty Japanese noir. The two threads of the story are connected, but only by coincidence, and thus the film has two unmatched halves. The first is more engaging; the second has its moments, but is fairly routine and doesn't have much of a payoff. The revelation that it seemed like it was building up to was more interesting than the one that was delivered. But the film has a lot of flashy noir style, with some wonderfully framed shots, and the two leads are quite personable.
