Well, to quote slashdot...
(not for the faint of heart!)
Imagine a modern hog factory farm, imagine the veritable rivers of semi-liquid feces squelching downhill from the oinking, shuffling pigflesh. Imagine a rope around your leg, the far end attached to a speedboat. Imagine being pulled backwards through that stinking mass, mouth clenched tight against your bile but still the runny sht makes it up your nostrils and down your throat, between your eyelids, burning your retinas, the impact of the brown waves against your body like sledgehammers.
If you can tell me what's so bad about that, I can tell you what's so bad about Uwe Boll movies.
