An impressive HK movie from a new generation director. Different from the traditional HK movie which is full of action scene, this is more to the artistic side with stunning visual arts effect in competitively slow pace. The background music is also any key to this movie which creates the horror and mysterious atmosphere. At the last stage the pace becomes faster and is most interesting. All the actor performs well and did their job, particularly Anson Lo is a newbie but it doesn't shown like he is green. After all, this is a good movie, if someone like horror movie this is worth to watch. The story line is quite easy to understand.
