Forget about Kuleshov effect and embrace the Sheffer shot.
More about documentary and video art of fiction I'm used to, I find totally disturbing and depressing the landscapes Korine is showing us.
Those kind of landscapes always catch my attention,have always seemed to me like old sets, abandoned and where evil lurks. And in Trash Humpers are very marked by the use of the camcorder, which gives an even more creepy.
Well, obviously, having four morons, looking bad and dressing worst, destroying everything and singing, help, but for me the really crappy here is the landscape.
