Being a great fan of horror, especially Asian horror, I have seen tons of movies, but this one is outstanding. Why? It does have a plot (which is unfortunately quite rare among horror movies). The actors did a good job. It feels like a real documentary film (even if it's not). It does not get boring for a moment. The director cleverly combines the plot with the acts of a certain Japanese magic cult (perhaps this cult never existed, but still, it's believable). It reminded me of the similarly great movie "Forbidden Siren".

To me the one and only annoying thing about the movie was the character Hori, the psychic, but this is subjective.

I recommend this movie to all fans of quality horror.

9 out of 10.
