I can't remember whether I already knew the twist when I first watched this film, however many years ago (it wouldn't have been too long after it was released), but inevitably that was uppermost in my mind on this long-delayed second viewing, brought on by my current interest in ghosts - in which vein, the solution of listening to what they have to say was resonant. This is a good movie; there's a reason why it's become so much a part of the culture.
