KIDS is not a Korine film. It's a Larry Clark film, exploitation, a waste of time, really. I was afraid to see more Korine, too, after KIDS, but I took a deep breath and Netflixed Gummo. And my outlook on cinema probably first started to change with that film. Though boring in some places, it's so visually striking you can't help but be moved. There's no room for indifference.
Korine is much better than this. He has a sensibility where he is able to capture reality. It's shocking in a sad way, but still reality. If you've ever been fond of any sort of poetic sensibility in film, say that found in The Brown Bunny, Morvern Callar, Gerry, Songs from the Second Floor, check out Gummo and then julien donkey-boy. Both are worthwhile for the open-minded. Though the films I've listed don't have too much in common with Korine's work, in spirit they are quite similar.
