Injecting a professionalism by the use of synch sound, Alfred Cheung's finer points in the comedic interplay between the Mainland Chinese and Hong Kong characters might not get across but a basic understanding of the different mind sets is enough to appreciate Cheung's funny scenarios here. This includes a political singing match up between the respective sides in the conflict. In this case between Leung's father, played by a terrific Lam Kau and the Mainland duo. Cheng's famous rapid fire delivery gets ample time to shine and she embodies the not so always feminine and dedicated Cheng Shih Nan wonderfully well, even nailing a felt emotional core of the film she shares with straight man Leung. Brewing underneath are serious considerations about why the two sides can't come to terms at this point in time. All well handled and injected into an entertaining package by director Alfred Cheung who also lets Chin Ka-Lok action directing talents speak volumes at appropriate times. Also with Lam Chung, Sunny Fang, Emotion Cheung, Deon Lam, Sai Gwa Paau and Walter Tso (Carol Cheng's real life father).
