This movie is based on the true story of a Chinese serial killer who murdered and then mutilated 13 female prostitutes in Mainland China from 1991 to 1996. In this particular film the murderer is named "Lau Shu Biu" (Kwok-Pong Chan) who suffers from an insatiable need for sex which his wife (played by Farini Cheung) is unable to completely satisfy. As a result he visits prostitutes and subsequently kills them in the insane belief that he is helping them to achieve happiness in another life. Now, whether that was an actual motivating factor on his part is not known to me, but in any case the movie devoted quite a bit of time and effort depicting him slicing off certain body parts afterward to satisfy his depraved urges. Too much time and effort in my opinion. If that wasn't bad enough, this film also lacked any real suspense, mystery or excitement which ultimately resulted in a movie that I found to be rather long and boring. Brutal, raw and disgusting to be sure-but rather tedious all the same. In short, about the only thing going for this movie was the presence of Yuk-Mui Yeung (as "Jade") and the aforementioned Farini Cheung who lent their beauty to an otherwise repulsive picture. But other than that I found very little to commend this movie for and I have rated it accordingly. Below average.
