Where almost every other movie I’d seen wound things up, “L’Avventura” wound them down. The characters lacked either the will or the capacity for real self-awareness. They only had what passed for self-awareness, cloaking a flightiness and lethargy that was both childish and very real. And in the final scene, so desolate, so eloquent, one of the most haunting passages in all of cinema, Antonioni realized something extraordinary: the pain of simply being alive. And the mystery.
