Horror films have their own special guidelines when it comes to plausibility: basically, there aren’t any. And the Japanese flick *Ju-on: The Grudge,* which had a limited American release earlier this year, takes even greater liberties in the credibility area than most. Fortunately, writer/director Takashi Shimizu has enough tricks up his sleeve to make you forget that he’s not making one whit of sense. Logic is never a strong deciding factor, anyway, when you’re looking for a flick to give you goosebumps, which this one does, if only in moderate measure. Plus, creepy as it sporadically is, you can poke fun at it, too: The rage is coming from inside the house!
