What about Koreeda's Distance, or Canary by Shiota?
Thank god Germany was reunified.
Could easily have been de Palma's best. Too bad he included those shrink-explains-it-all sequences.
At first I was like "HEAVY-HANDED SOCIAL CRITICISM", 30 minutes later I was choking on that comment. The most visceral film I've seen in a quiet sometimes, and also one of the most painstakingly detailed. Watch it during the Olympics.
The world would have been a better place if all hostage films were this good. And for that matter if all attempts at observing a different culture were this accomplished.
Wakamatsu's United Red Army should be of some interest as well even though it doesn't deal with Aum.
Dreamlike, trashy and humane at the same time, probably Rollin's best. Also the incredibly incredible but brief urban montage shots are later expanded into a whole movie in Lost in New York. Too bad that the last ten minutes of that movie are just plain silly, and not in a good way.
Truly the greatest film ever made.
Feel-bad satire, made me to laugh then feel like an asshole for doing so. Does a fine job of bringing the latent insanity of the batshit insane world we're living in to the surface but for a superior film about this issue check out Reflections of Evil (the similarities between the two are simply striking. coincidence, right?) and Khavn would have done better if he didn't rely on familiar sex/violence tropes too much.
