This film essentially begins with a YouTube blogger by the name of "Akina" (Rinka Otani) recording herself as she enters a thick forest known for the number of people who venture inside to commit suicide. While she is recording, strange things begin to happen, and her screams are the last things anyone hears. The scene then shifts to a teenage girl named "Hibiki Amasawa" (Anna Yamada) watching the video at home and becoming quite disturbed by it. Not long afterward, while helping some friends move into a new apartment, a strange box is found under the house which terrifies Hibiki--and immediately afterward the people around her begin to die in horrific ways. Now, rather than reveal any more, I will just say that I was extremely impressed with this movie--for the first hour or so. Unfortunately, the plot began to drag to such a degree that I almost felt like entering this deadly forest myself. It was almost as if the director (Takashi Shimizu) decided to abandon any pretense of a plot and simply fill in the remaining minutes with special effects instead. That being said, while I don't consider this film to be that bad necessarily, I do consider it to be a missed opportunity, and I have rated it accordingly. Average.
