My motivation for this comment is the only, very negative review, that says exactly the opposite of what I found in this movie! The overall rating is terrible (though 11 votes is not representative of anything), and the film definitely deserves more.
To me, it has a good story, for once. It avoids Asiatic horror movie clichés and creates a mood of its own. It is superbly photographed. Under a seemingly classic form and approach lie lots of elements that makes this movie much more special than you'd expect it to be in the first 10 minutes.
It's well worth a try. To be perfectly honest, I saw it in a festival, and one develops a certain tendency to see the good things in the four to six movies you watch every day, so I can't rule out that I might react otherwise if I saw it today.
Still, I am confident this is more than just another Asian horror-flick, and that, if you're curious and open-minded, you'll find something to feed your movie-hungry appetite...
