text: One of the most nihilistic and brutal films I've ever seen, but also one of the most tragic and moving ones. This is an action-melodrama like the world has never seen it before. Sometimes the plot got me close to tears, while in the next moment delivering shocking revelations like a bone-crunching blow to the guts. Chilling performance by Edison Chen. The story of a HK-Cop and a Cambodian killer hunting each other down, while bit by bit losing their humanity, is a strong one. Featuring very little dialog in favor of haunting imagery and gritty camera-work, "Dog bite Dog" is pure HK-Bloodshed without the Heroism.
