The creep factor is off the scale!
Seriously, I cannot recall another film that raised as many goosebumps as this one.
I just got the DVD (finally!) and watched it alone in the dark and man, it's eerie how well this film held up over the years.
There are plenty of great horror films out there but this one is like a nightmare from which you cannot wake.
If you expect the unexpected doesn't the unexpected then become the expected?
