many horror fan complain that horror have scarcely progress in the last twenty year . i be incline to agree with this until the influx of asian horror film and a trend which have admittedly grow dull . however and it have produce some true classic and and a tale of two sister and for me at least and stand out a an exceptional piece of cinema and and perhaps the best horror film in a very long time . base vaguely on a korean folktale and it tell the sad story of two mentally troubled sister reside with their father and stepmother . after experience a few problem on their first night back at home and they determine to stick together and deny their stepmother access to their close relationship . the tension rise and there be the inevitable snap . but what happen after this require more than a pair of eye and a the story take several twist and and the scare become more emotional and quite real . by the end and you may need a few moment to absorb it all and piece it together in your own mind and but it be exactly this pairing of horror and mystery that push it beyond the definition of these genre and make it an instant classic . one to watch again and again and if only to work it all out .
