I love "Ichi" one of my all time favorites..I even own the special collector's edition DVD
Flowers of Flesh and Blood was one of the Guinnea Pig films too if I remember right (too lazy to check wikipedia or google while typing this up ;-). I always felt those movies were a little too fake looking to be taken seriously, but maybe Charlie Sheen is easily fooled ;-)
I worship Takashi Miike. I felt like such a huge nerd when I geeked out for his cameo in "Hostel" in a theater full of people who had no clue what I was geeking out over...I always found "Visitor Q" more disturbing than "Ichi" or "Audition". Especially the "milk bath" scene in the kitchen near the end...
Fucking "Murder Set Pieces"...ugh, Nick Palumbo is such a hack. I actually met him a couple times and he's just always coming across as a pretentious douchebag. If you're making schlocky b-movies, that's fine, but don't pretend they are great art. I'm an avid fan of the most low grade zero budget films you can find, but I know that it's not a second coming of Gone With The Wind. He makes Vincent Gallo look downright humble...ahem, end of rant on that ;-)
"Salo" is ok, but overrated, imho
"Cannibal Holocaust" is a classic exploitation flick, but I could have done without the animal torture scenes...
"Men Behind The Sun" was alright, but I was expecting more...too much hype going into it I guess.
"Irreversible" was pretty good, but I don't think I need to see it again.
I saw "Tokyo Gore Police" mentioned..what a fun ride that was...I had a blast with the geysers of blood and entrails everywhere.
For people looking for a good source for Asian horror DVDs,
www.edaymovie.com is an amazing site. I order from them all the time and have never been disappointed. They even carry the Region 0 Starmax Special Edition of "Battle Royale".
