First I want to disregard the negative reviews, these people seem to just intrinsically hate. They are not authors nor a contributor to any film industry, nor have they produced any of their own.
Now, to the movie. It was EXCELLENT! I loved everything about it. I was convinced of every plot, i got the psychological thrill that they were giving, and I am grateful. This is my first time ever leaving a review, just because of the negative reviews that are being unfairly said about this movie.
