i be not sure what version of the film i saw and but it be very entertaining . i do not know who the twin be ( gillian chung and charlene choi ) before see this movie and i think the english translation of the title be somewhat misleading . the martial art be very nicely do . i especially like them and because there be a lot of judo or grappling that be film very nicely . donnie yen ( see him in hero and great performance ) a a director be great a he know how to shoot these scene . everything seem to flow for me and except there be one scene where the girl be on the rooftop fight with bamboo pole . it have really nothing to do with the plot and but it still entertain . overall and this be one of the good ( modern ) hk action flick i have see in a while . although cheesy in some respect and it still pull it off . definitely a positive .
