Many Hong Kong thrillers suffer from over styled over produced (by Hong Kong standard) and over acting. I feel like this one has none of those and it has a good story and direction to back everything up. Nick Tse is a pretty boy but this flick he plays a man all right. The film was released in 2008 and I just caught it in 2020. I have no expectation after seeing too many thoughtless glossy productions, but this one is an exception and a pleasant surprise.
