The original story contained many great things. It was built upon a wonderful fictionary world of many events, which are connected with what we are seeing now in old books about Buddhism, or in many statues in the pagodas. It explains the true meaning of the scroll, and many hidden philosophies of the two parties: Jiang Zi Ya represents one party, and Shen Gong Bao represents the other one, and why they became oppositions, why many Buddhas have their animals to ride on (as we can see from many photos in the book or the temples or pagodas). The original story also mentions that a new Kingdom will be born and led by a new King. It is totally different in this movie: the new King will be the hair of the throne of the old one, who is a bad King (King Zhou of Shang / Di Xin).
It is too bad that the team could not keep the story as close as the original one. It turned out to be a very conventional story, nothing is special.
Maybe in the future, we will have a chance to see the original story in the movie(s) rather than a movie uses the characters and some events from another old book.
If you come to see a movie as someone who doesn't know about the original story, you might enjoy it because of the visual effects, actors, and music.
But for me, it is just a movie without a soul!
