I Spit On Your Corpse (1974)

Imagine No Country for Old Men, but with gratuitous nudity, few, if any, logically behaving characters, painfully awkward dialog and rampant feminine criminality. If you take all that, wrap it up in a gift box that feels a lot longer than it is, and add a kick ass soundtrack that is Lalo Shiffrin meets Ennio Morricone and Muzak. That is I Spit On Your Corpse aka Girls for Rent.
