Asian horror can't go on much longer adhering to such standard rules, but for now it's frightening and effective.

[It] may be a rather unmemorable addition to Asian horror, but you'll be far too spooked to hang up before it's over.

If you're a fan of modern Asian horror, I'm sure you'll check it out anyway, just keep in mind that it may not be as effective as you hope.
