Obviously because this is choreographed.
If you qualified the movie solely on the fights you missed the Tai-chi morale, not that is grandiose delivered in the film, but is worth of mentioning, because of the journey of the "hero and antihero" did, and the struggles (because he decided so) to find his internal balance.
UFC is choreographed? Any source?
I picked fights because it was the only thing that was better than bad in this movie. Anyone else found montage awful? Also all the 'clues' and hints (for ex. Good hero dressed in white, bad guy in black) were so pretentious that it almost felt offensive at times.
If I wanted to learn about Tai Chi the last thing I would resort to is action movie lol. With modern Web it is so easy to find boks, interviews, even portals about Tai chi that going for info to some action, fighting movie with Holywood star or anything than useful metaphors is ridiculous.
