Ju-On: The Grudge 2 (2003)

A direct sequel to his earlier JU-ON (2002), this finds Takashi Shimizu offering us more of the same brand of chills, shocks and guttural throat noises.  Unwisely though he clearly felt he had to up the ante with the result that the film feels less together than the previous one and more a succession of set pieces.  The spectres are seen more often, and earlier, thereby reducing their impact.  Recognising this, Takashi gives them new powers - like the ability to crawl across ceilings or rise up through the floor.  The net effect of which is to make the apparitions seem less like hateful but tragic ghosts and more like indestructible franchise super-villains, a la Freddy Krueger, Michael Myers and Jason Voorhees.  The nadir is reached when one character gives birth to a full grown female spectre, which proceeds to butcher all the nurses.

In summary, JU-ON 2 is to JU-ON as THE FLY 2 is to THE FLY.
