I guess I would have to disagree about the characterization of Hero as a kung-fu movie. At least in my mind that conjures up images of Bruce Lee / Chuck Norris extravaganzas.I think Hero is a very thoughtful movie, and I whole heartedly agree with the use of the word elegant. In some respects it does pay homage to what we've been accustomed to think of as "typical" martial arts movies, but I believe there is was a serious intent to express quite a bit more about nobility and sacrifice than is present in the run-of-the-mill karate movie.
Well worth the money, time and effort.
