There's a Korine interview on The AV Club. I guess he doesn't come across as quite as much of a jerk as I would've imagined, but reading the interview really confirms just how much I don't ever need to see one of his movies.
Yeah, I think he get's kind of a bad rap. I have absolutely no interest in seeing Gummo or Julien Donkey Boy, but I certianly don't think he does what he does just to be a deliberately transgressive avant garde darling, or whatever other levels of phoniness people accuse him of inhabiting. I'm not sure what kind of all-powerful Avant Garde Establishment people accuse him of trying to impress all the time, but in the interviews and stuff I've read about him, he's usually able to speak pretty clearly about his art and why he does what he does and all that. I think he has genuine artistic reasons for doing what he does, even though most of what he's involved with seems annoying and/or totally repulsive.
It's just hard for me to believe that someone would spend a year or more of their life financing and shooting a film where every day on-set before they yell "action", they think to themselves "I have no idea what I'm doing and I don't give a shit, but this is going to drive my avant-garde cred through the
roof! I can't believe people are gonna buy this shit!"
The only film of his I've seen is Mister Lonely, and while it was pretty flawed and boring in parts, Richard Strange dressed up as Lincoln maniacally reciting the Gettysburg Address in front of strobe lights while spinning a basketball on his finger was one of my favorite cinematic images from 2008.
