The density of the black and white is incredible. The camera angles and reflection shots are unsettling. The score is appropriately terrifying, from the ringing of tiny bells to the cannon ball rocking down the hall.
The cast is excellent. The direction superb. This is horror at the peak of perfection--it is in your mind. The only thing better is to read the book by Ms. Jackson on a dark night when you are all alone, and "far from town." As Stephen King said about Shirley Jackson, "She never had to shout." Mr. Wise is to be credited with bringing her whispers to the screen.
Rent this for Halloween. Or, own it forever. I still have trouble getting to sleep after I watch this.
