I was actually very hopeful for this movie. The first 30 minutes or so really had me going. Good plot, decentish acting, creepy antagonist, "make you jump" scenes. Everything that makes a scary movie, well, scary.
But then it turned into a wreck. It's as though the actors forgot how to act. Perhaps it was because there was little premise before the movie began to climax, so the mystery factor was taken away.
By the end of the movie I was just shaking my head and wondering how such a promising movie went so wrong.
