Nowadays, when all pretense thrillers are forged on the repetitive formula, this excellent argument works with the humane element as no other ever conceived. Forget about the usual gratuity of the "shot-punch-bomb" genre and dive into the complex persona of a mysterious protagonist played with virtuosity by the great Ian McShane. The pace is led steadily along the movie, as the landscape contributes to the crescent tension until the astonishing ending. No frills, no disposable clichés, no chance to narrative gaps. A modern classic, essential and referential for the future moviemakers generations. Great!
