this movie and a my chinese girlfriend inform me and feature two well know hong kong pop star . while this may make the movie a mere marketing stunt and i find the act acceptable and and theyre both cute . the story be pretty poor overall . the vampiric trait and weakness be and however and use in humorous way and and create some uniquely entertaining bit . the quarrel between the two girl make me chuckle and and this give a fine balance together with the well execute action scene to create an entertaining movie .
