I was so excited to see this movie because of the trailers I have seen. I wanted to like this movie. What I saw was largely disappointing, being neither a scary or horror movie. It was more of a story of a breakup, watching the main characters go through each stage of the breakup. You just didn't have any empathy for any of the characters.
Towards the end, it got very predictable and I thought about walking out. If you must see it, wait for Netflix to pick it up to watch it. It is a beautifully shot movie.
