this movie is made for Asian/Chinese market, targeting particularly fans of Jay Chou, one of the biggest music star in Asian.

Jay Chou is a very talented song writer/singer. He is mediocre as an actor, although he did appear in several big-budget productions ("initial D", "Curse of the Golden Flower "). Amazingly, he won both golden horse (taiwan) and Hong Kong film awards for "initial D".

The supporting cast are very well chosen, which appeals basically everyone from China. The cast including many famous movie/TV actors, singers, even sport commentator (Huang Jianxiang from China). However, they were not given enough time to show their talents.

The biggest mistake is that Chu took over both director and writer position. He has a reputation of making shallow and brainless movies based off non-coherent scripts. With his poor directing and lam story, the whole talented cast, fancy vision effects and tones of production money was wasted.

However, the terrible movie successfully cashed in over 10 million dollars, maybe even more in Asian, which made this one of the biggest box office success in Asian.

The bottom line is: you can watch this movie only if you want to see how money and talents are wasted, or if you are simply accompanying your kids who are fans of Jay Chou.
