It isn't very good. The idea sounded good but the story is just bad. Donnie Yen wears a costume that makes him look like Kato or Jet Li from the Black Mask. The fights are all undercranked. They were just trying to ride Donnie's popularity from Yip Man.
This was playing on a TV in the store window of an Asian video store I walked past last week. I watched a few minutes of it. They took Fists of Fury/Fist of Legend and made it into a really dumb superhero movie. I guess the fighting was alright from what I saw, but the story sure got turned stupid. I wouldn't buy it, but watching it for free in the store's window was a good solid 10 minutes of entertainment.
