This film which inspired Hollywood's 'Mirrors' has some visually striking and genuinely creepy moments, along with some excellent suspense (although the tension-building music was overdone at times). The lead actor didn't seem to be very into it but the rest of the cast do an above par job. The movie lags a bit and becomes increasingly more dialogue heavy towards the end yet the main character doesn't become any more interesting. Still, there is more depth to be found here than expected.

Conventional, not very interesting, horror movie. This viewer did not make it to the conclusion.

Visually inventive but mostly uninspired Korean horror film. Starts out surprisingly good then gets duller and duller by the minute.
