I purchased The Grudge 2 unrated directors cut. What is the difference between the original and the unrated?

it says on the case "Includes scenes to scary for theaters." what happens and how are they so scary?

director's cut DVDs have a few minutes of extra film in them, which was cut from the one they show, mainly for formatting and time constraints. They should also have extra scenes, too.
