The most unintentionally humorous thing about “Shutter” is how easily everyone grasps the concept that there’s a very angry female ghost stalking them via Tun’s photographs. A photographer by trade, Tun always carries his trusty camera with him, snapping pictures whenever he gets the chance, and it’s through this vessel that the ghost seems to be making her presence most known. In the aftermath of the accident that may or may not have been real, Tun starts seeing odd over exposures in his photos. Without missing a beat, Jane immediately surmises that a spirit is haunting them, using the photos as a means to pick her victims.
