Not that i've seen every Asian horror movie out there of course. i've seen most of the biggies though - ring, ring 2, ju-on, dark water, cure, plus some others i can't remember the names of, and this is up there with the best.
Style-wise its not very original and borrows heavily from the Ring in its presentation, but whats wrong with that? Especially when its done as well as this. It's also scarier than the ring in terms of jump-out- of-the-seat moments, though it doesn't have any scenes quite on a par with the ring's freaky crawl out the telly scene, but then that's probably the best horror scene ever so I can forgive it for that! As well as the scares you've got good acting, good well structured plot and a really great ending - I didn't see it coming at all.
In conclusion, if you liked the ring you will love this. 9/10
