Directed by Richard Linklater from Eric Schlosser's 2001 bestselling exposé of the McDonalds conspiracy, the 2006 Fast Food Nation is an anti-commercial. Taking a cleaver to the great American hamburger, its designed to kill desire and deprogram the viewers appetite. Fast Food Nation opens with a slow zoom into the fresh-charred heart of a greasy, gristle-flecked beef patty. The thing looks disgusting long before its established that any individual burger is the ground residue of many, many messily butchered animals (plus their hormones and the contents of their intestines), given a dollop of extra fat, injected with chemical perfume, and possibly dipped in floor dirt or garnished with an employees loogie. Linklaters polemic is overflowing with good intentions and its graphic enough to put you off beef, but the director is actually after bigger game: He uses the scarcely fictionalized Mickeys franchise (Home of the Big One) as a metaphor for American life, because McDonalds R Us.
