Keizoku/eiga [Keizoku: Unsolved Mysteries - Beautiful Dreamer] is an extension of a popular Japanese TV drama. Usually these kind of films tend to be a little lame. Easy cash-in on an established brand, dragging out a regular TV episode to full feature length. While this may still be the case with Keizoku/eiga (I never watched the original series), I think that would make the TV drama one of the more interesting productions ever to have aired on TV.
Helming the film is director Yukihiko Tsutsumi, who enjoyed moderate international success when he entered a directing contest with Ryuhei Kitamura and produced 2LDK as a result. Tsutsumi is a rather hard to coin director, continuously on the lookout for new challenges. He isn't really bound to a genre or medium, the only constant is that he's always busy. Keizoku/eiga is one of his earlier projects and it bears all the markings of a young director.
The film follows the adventures of a police squad trying to unravel unsolved mysteries. Perfect material for a TV series of course, with a new case ready every episode. If that sounds a little stale, not to worry, Tsutsumi turned Keizoku/eiga into a surreal and sometimes even absurd mystery. A clash of styles, blending comedy, police thriller and arthouse all into one restless package. The result may not be very subtle or sensible, it sure as hell is amusing.
The color palette is a little dire, with lots of murky greens and blues, but there's quite a lot of visual experimentation to keep things appealing. The plot is convoluted and quite effective, but ultimately the film itself seems to lose interest in the mystery to solve. The big reveal is made almost 30 minutes before the actual ending, with the crazy post-finale eclipsing the entire mystery that was set up before. I'm sure not everyone will appreciate that, but if you're still expecting this to be a basic police flick 90 minutes in, you've probably been dozing off more than a few times.
Tsutsumi never fully manages to bring all the different elements together elegantly, with the comedy and arthouse bits clashing violently from time to time. Like I said before, Keizoku/eiga isn't the most accomplished film, but it's never boring and has plenty of surprises packed to keep you engaged throughout its entire running time. Warmly recommended if you like weirdness and can bare some unevenness in the process, if you want a more solid experience it's better to look elsewhere.
