In the tradition of the latest good martial arts movies coming from Korea, this one really doesn't disappoint. The plot centers around an ancient secret weapon based on Chi guarded since ancient times by a secret society... The man character is an honest, pacifist, almost inept and at times strange, policeman not aware of his unknown strengh who seeks to learn fighting for revenge. There is a lot of CG in the movie but contrary to many Hollywood (and non-Hollywood) movies, the CG blends very well with the rest of this fantasy movie and add to the stunning visual appeal of the film. The movie has some very funny and surprising scenes, and many action-packed sequences. The fights are very well choreographed. I would give three thumbs up if I could...
