Fantastic and original. I think the thing that sets this movie apart from other Found Footage films is that it is highly reliant on a "behind the scenes" aspect, with the added scares from most other FF movies.
I'm not able to go into too much detail without spoiling the movie, but the origin of the ghost or creature for this film was very original and I have not seen it done before, at least in FF.
It does have a bit of a slow build up to the actual scares but I think it was worth it to build on the idea of how the evil in this movie is created.
If you are into FF and especially Japanese FF I highly recommend it. 5 stars
