I'm sorry to break to you, but this movie is really terrible! I saw it at SIFF this year and it was my biggest disappointment. It looks like it was made in the early 90's in terms of bad CGI effects and the martial arts were very lame. The story is laughably bad. It might make a good midnight MST3K style mockable film, but don't expect it to be good.
Couldn't disagree more with Z. This movie is a blast. My jaw dropped several times while watching it because of it's awesomeness. Great acting, beautiful costumes/sets, and wildly imaginative.
Tsui Hark has been making fun HK action films before most of us were born. Mrs C&B and I saw it and agreed that it fits comfortably among Once Upon A Time In China or Warriors of Zu; full of cliche but entertaining in a big budget sense. I think most fans of Chinese action/fantasy films will enjoy this.
