Filipe Furtado’s review published on Letterboxd:
The land of opportunities. When violent men meet an unforgiving city. Some very good character work with the mainland criminals and great location use. This is the least fun super violent Hong Kong of its era. The violence is raw, the sense of collateral damage far too real, as is the paranoia and doomed atmosphere. Everything just goes bad and escalate, desperate criminals who are trigger happy and then a militatized police force that believes in shoot first ask what is going on later. Those final scenes in Kwaloon City very enclosed space get near horror movie territory. Suddenly we are in a stalk and shoot film, fully identifying with the criminals serving as target.
