Script is kind of ok, but directing is quite bad, that makes the movie boring and lacking of intensity. Except for Michael wong's good performance, the rest of the cast performed quite badly and unpolished, where they are stiff and lack of emotions. The silly dialogues are like book reading instead of actual conversation, which makes the movie unconvincing and damages the viewing experience. However there's one good thing about the movie, that shows how negligent and unethical the hk police are, trying to sue and pin the crimes to innocent people, which is why the become the city's most hated.
