Not quite as good as it gets, but really, really good.
A great movie. One you will watch multiple times. This should be the minimum standard for horror films.
A really, really good horror movie. Close enough to the minimum standard to earn multiple viewings.
A good film. Worthy of your regular list or at least checking out to see if it works for you.
Movie is so-so. Not a must see or maybe even worthy of recommending, but a film that will likely keep you watching through to closing credits. A lot of horror films are here.
The beginning of the suck zone. Not completely sucky - has some redeeming features - but kind of sucky.
Movie owes me part of my life back.
