I really enjoyed this movie, having never seen nor heard about the Japanese manga it's based on, I can't compare this movie to it, therefore as a supernatural thriller, it's not a horror movie to me, it was very entertaining, something very different and it kept my interest throughout. The ending was unfinished to me, therefore leaving a window open for a sequel. I'm hoping there will be a part two, I'm intrigued. However seeing the number of negative reviews that might not happen, most negative reviews are from people who have seen the Japanese manga. I say give it a try, check it out, you should be entertained.
