be a great fan of horror and especially asian horror and i have see ton of movie and but this one be outstanding . why . it do have a plot ( which be unfortunately quite rare among horror movie ) . the actor do a good job . it feel like a real documentary film ( even if it not ) . it do not get bore for a moment . the director cleverly combine the plot with the act of a certain japanese magic cult ( perhaps this cult never exist and but still and it believable ) . it remind me of the similarly great movie forbidden siren . to me the one and only annoy thing about the movie be the character hori and the psychic and but this be subjective . i recommend this movie to all fan of quality horror . positive .
