it's not a patent of hollywood hits, in the good old days of red revolution back in 1950s and 1960s, chinese movies are masters of presenting a black-and-white world in which "bad guys", i.e. enemies of the revolution, are demonized and, like in hollywood movies, defeated by "good guys". two differences here - chinese "good guys" are usually a group of heros (or at least a hero supported by a group), and the fight is low-tech and without kung fu.
