A gang ofelderly morons have sex with garbage. What more can I say about Trash Humpers? Maybe that desperate provocateur Harmony Korine shoots with insouciant ugliness on the crudest possible video format. (Like "found art?" Is this the Cloverfield of underground filmmaking?)
And that the old people are not really old but young people in crummy make-up with irritatingly fake old voices. (Okay, there are a couple of genuinely old and unpleasant persons in it.) And that in addition to humping trash, the characters hump other inanimate objects, recite scatological poems, force victims to eat pancakes with dishwashing liquid, philosophize ("We choose to live, like, free"), drag dolls behind bicycles, and kill people.
And that the film might have been shocking had it been made about 50 years ago, before Andy Warhol and John Waters and others had squeezed everything of interest out of the genre. One-time enfant terrible Korine hasn't gotten old. He's just gotten more puerile.
