During a pre-screening Q&A at the Tokyo International Fantastic Film Festival, the interviewer describes watching Dead Leaves as like eating raw meat in the morning - I don't think I can come up with a better analogy.
The film grabs you by the balls and doesn't put you down again for its 50 minutes duration. There's zero depth - no time to think, barely time to draw breath - just time to let your senses be pummelled by some of the most insane, frenetic animation ever committed to screen.
Harsh, but watchable.
Dir. Hiroyuki Imaishi, 2004
