The advanced techniques of the Hong Kong action
cinema translated from the period kung fu and wuxia film to the
modern world of cops and robbers, from swordplay to gunplay, not for the first time (it was preceded into the present by Jackie Chan's Police Story from the previous year, as well as
Cinema City's highly profitable Aces Go Places series of comic adventures and a whole host of films from the Hong Kong New Wave like Tsui Hark's own Dangerous Encounters - First Kind, not to mention earlier films like Chang Cheh's Ti Lung - starring Dead End, from 1969), but better than
anything before it.
