If you go into this expecting a ghost/horror movie you'll be disappointed; if you go into this expecting an action movie, you'll be disappointed; if you go into this expecting a gripping suspense movie, you'll have your socks knocked off.

I don't want to compare this to Hitchcock, because it's something different. But there are plenty of touches here that the Master would be proud of.

Excellent performances all around, but an especially strong performance by Lau Ching-Wan. Very much recommended.
