1. This film has no Gore. If you are into that skip it.
2. I enjoy the understated nature of this film. Some argue that is a weak argument for poor writing. I disagree.
3. I have seen so many horror films it is difficult to scare me. I watch these films to see the story unfold. So I can't speak to how scary it is.
4. I enjoyed the interaction between the actors especially the guy who shows up mid movie. His indifferent behavior and rudeness kind of reminded me of a manga character. In a good way.
5. I thought the way the spirit was portrayed was both bizarre and strange and seemed realistic to me. If you actually met an evil spirit I mean really met one it could look like that. You don't know.
6. I disliked the strange faces in the beginning they looked like stock image.
7. I disliked that they never really explain Ed why the girls were taking on such a strange job. Maybe i missed it. Or maybe they were just broke needed the money and didn't ask.
8. It left a number of unanswered questions at the end. I wasn't sure if that was a deliberate cliff hanger and there is to be a sequel or not but I wanted a more solid end. But based on my theories about the male character it could make sense.
All in all I think you should watch it if you like found footage style films, don't need blood in your horror, and aren't annoyed with not full closure endings. I can't compare it to Noroi because that is a different movie on a different level. I also think his films get lower reviews because everyone compares it to Noroi and you shouldn't do that I mean that's like comparing two different kids.
