For the most part, the action is reasonably entertaining. There are still frequent moments where physics is ignored to the detriment of believability, but it's actually better than the action in most kung fu movies.
The worst part is that there isn't any emotion behind the fights because the movie dives into the action too quickly without giving the audience a chance to relate to any of the characters. The dialogue was so brief, rushed, and emotionless that it felt as if the director's only goal was to show off the cool fights he came up with, so he lazily tied them together with a hasty story that only serves to get us back to the action as quickly as possible.
