I'll be the first to point out that if you're a fan of the 'Ju On' series of films or something similar, you may find this a disappointment. It has a few creepy moments but overall it moves a steady, gentle pace to allow for the story to unfold. The 3 main characters at the foreground of this movie (Sayori, Hinako, and Fumiya) are each quite intriguing and flawed. But i'd have to say the character of Sayori is the most developed and faceted while the other 2 merely support her and the plot.
Now this was not a complaint of mine but of the boyfriend that watched this picture with me. So this may bother other would-be viewers. It is mostly shot with what seems to be a hand-held camera so it will wobble and shake. (Please correct me on this as I am unfamiliar with the many cameras and styles of shooting.) In specific moments of the movie, it seemed to add to the suspense. I thought they did a fair job of setting the mood as well. There were just a couple of times where say background music that had been edited in seemed to loud or didn't quite settle in with the flow of events. Particularly during some personal exchanges between Hinako and Fumiya.
The basic premise of this movie is set around Hinako, whom moved away from Shikoku as a little girl and has returned to take care of family business. She left behind 2 childhood friends, Sayori and Fumiya, that she was hoping to see again as well. Unfortunately she finds out that Sayori died when she was in high school and her mother, the local priestess lost her mind and has been on this pilgrimage for the past 8 years to visit the 88 temples on the island. Naturally strange things begin to happen once Hinako has started to settle in. She and Fumiya together start to investigate. Much to their horror, they find out that this pilgrimage Sayori's mother has been doing is apart of a ritual which would turn the island into the land of the dead!
