An absolute masterpiece. I wish I could rate this higher than five stars. An essay on modern life and on cinema itself. By reducing your perspective to Stewart's eyes, the camerawork makes you feel both helpless and complicit in the sort of voyeuristic behavior he indulges in. Just like Jeff and his neighbors' lives, you too can't take your eyes off the screen. The unparalleled Mr. Hitchcock at the top of his game.
