If you watch this movie for the action and the story telling, it is a great movie with great messages. You will sure be entertained from start to finish. If you watch this movie for it's historical context, you will sure be disappointed. It was obviously an over the top story of a historical event in Bruce Lee's life and not meant to be historically accurate.
As alternatingly silly and serious as its mix of wisdom and wallops, and even with that blond bro gumming up the works, “Birth” is nevertheless zippy, B-movie entertainment.
The fight scenes are indeed the film’s strongest element, even if at times they seem overly choreographed and slightly cheesy.
