twin effect be a poor film in so many respect . the only good element be that it doesn not take itself seriously . other than that and this be not really a movie and but rather a merchandising tool for the film two star and popular pop idol in their native hong kong . the film itself be poorly construct and act . the direction offer up some silly martial art and which be odd since the action director ( and supposedly co director ) be donnie yen . like many hong kong film gear for the teen audience and the major fanbase of actor like the twin ( the two girl who star in this film ) and ekin cheng and there be so much bad music to prod the audience into believe certain scene be funny and clever and etc . the final conclusion represent it all for naught . even a a fan of hong kong movie and this be a poor film . not funny enough and not serious enough and and just generally too bubble gum fake for it own good . negative .
