What makes The Grudge 2 so bad? It goes without saying that it's a sequel, a remake and a remake of a sequel, which -- as far as Hollywood is concerned -- makes it a safe bet three times over. Probably less obvious is that the film continues an almost 30-year tradition of trying to re-create the success of John Carpenter's groundbreaking Halloween (1978), a pared-down scare flick in which the only thing that happens is a supernatural being hunting down and killing innocent characters.
But there's something else going on here. Horror movies are the ultimate in "body" cinema, or cinema that we experience physically, rather than mentally or spiritually. Because of this, nudity and sex have always gone hand-in-hand with the genre -- even before nudity could be shown. Look at Cat People (1942), in which the heroine turns into a murderous feline when sexually aroused, or the shower scene in Psycho (1960), the ultimate in vulnerability.
