This is what happens when some of the most talented and creative people in japanimation get really drunk. A vulgar, violent, sexy caleidoscope of an acid trip that is simultaneously a love letter to japanimation and a parody of all its cliches, set to driving Yoko Kanno beats. In short it's plain freakin' awesome.
This came out around the same time as Masaaki Yuasa's mindgame and even almost 20 years later both still feel like the future of animation. Yuasa with his sketchy lines and paintbrush beauty, Imaishi with his vector-like graphical clarity and excess.
The story of Dead Leaves is simple. Two convicts from a lunar prison facility, Pandy and Retro, awaken on earth with no memory of their past and immediately get pursued by the cops. Wickedness and shenanigans ensue.
It's definitely a unique trip and a good introduction to Hiroyuki Imaishi's aesthetic that continues to evolve and refine, as evidenced in the recent opus Promare which managed to gain a more mainstream audience than Dead Leaves will ever have. Which is by design mind you.
It's beautiful madness from beginning to end, gleefully indulgent in sex and violence which are both played for laughs and can be exhausting if you don't know what you're in for. That is not to say it's ever just random. Every frame despite the excess is drawn with a level of taste, purpose and clarity that is rather unique to this day. It's basically the visualization of a great electro punk album and a testament to the creativity of Japanese animators. A promise to the future by Imaishi that he continues to keep.
Makes for a great double feature with his more recent short "Sex and violence with mach speed".
