First hour and a half was a genius set up for a psychological thriller. Good acting, great music, interesting story line, stomachs turning to gruesomeness reminiscent of The Fly! I was excited for the ending because it could have gone in many directions! Then turned into an ultra violent blood fountain. Why?? What a cop out! Most disappointed ending to a potentially great movie I’ve seen in a long time. Did the director really want my gf and I to be laughing out loud at the end? It was ridiculous. Only one couple walked out, I was surprised it wasn’t more.
