The Grudge? or Ju-On?

Well...looks like another Japanese Horror film is getting "adapted" to an american version...

Gonna take my girlfriend to see it when it comes out, but I'm questioning how good it will be when it comes out stateside...after all, Sarah Michelle Gellar is gonna be in it...I really don't know how well that will work...

Thoughts anyone? I know the original is supposed to be incredibly scary.
