For years, American films have been inspired by Chinese and Japanese films. From Star Wars to Matrix to Kill Bill, and all points in between, martial arts films have been an inspiration.
Kung Fu Hustle takes all of those films, ingests them, and takes them back for to make a truly Chinese film. And makes it funny.
It is an awesome, awesome film. It is ridiculous and sublime, and eventually, even moving. And it has kickass action, laughs, great characters, and a pure sense of fun.
ps. Don't watch the trailer. Massive spoiling of fun scenes.
