andy lau play one of his most memorable character . his love for film and manga play nicely to the crowd . the use of 2 dialect in the film be nice . the third character ( the girl ) connect the two assassin in both story and dialect . in this movie you spend the time cheer for the bad guy and thrill their rivalry with the police and each other . in a showdown that everyone know have to happen between the two hitman you choose who you like throughout the entire film and then see who come out on top . an excellent film .
