Great opening, but got messy quickly, and ultimately was an unsatisfying 79 minutes. The frumpled lead character (48 year old Michitaro Mizushima) reminded me a little of Glenn Ford in The Big Heat and the befuddling, often nonsensical plot reminded me of The Big Sleep, but Seijun Suzuki's work lacks the star power and atmosphere of those films. Questions piled up for me as I watched, and not just about the sequence of events from one scene to the next, but about basic character motivations for pretty much all of these people. The grand reveal of Akiba near the end was silly and a letdown too.
I never began actively disliking it though, because I never really knew what Suzuki was going to put on the screen next. There's a topless stripper shot in the chest with an arrow, and a James Bond like escape from an attempted execution (when of course a simple bullet would have made so much more sense). One of the mysterious young women being tracked down loves American rock 'n' roll, and has a gang of teenage friends pile out of car to protect her. There are several murders, but the main character believes in the goodness in people, and improbably the beautiful young femme fatale (Misako Watanabe) softens and falls in love with him. It's an absurdity set to a jazzy soundtrack and doesn't really work, but somehow held my interest. You can do better though.
