Don't understand why rating for this film is so low. What criteria is used for such ratings. It seems horror films suffer from this most. I feel many otherwise brilliant horror movies are unfairly rated low. Some people, I feel treat movies as rocket science. It just has to be perfect and thick just about every box. Not every film is a "godfather" or "Dog day afternoon". Love this movie. Kept me at the edge of my seat at least 80% of the time.
