If you are a kung fu movie fan you can invite your Hollywood movie fan friends over to watch Killer Constable. Tell them it's an action movie that actually has a plot and a dark disturbing emotional impact. Yes, you could even watch this movie with your mom!
I like to analyze plot structure and almost all kung fu movies fall into four plots. 1) Revenge or "You killed my master" 2) The Karate Kid or doofus learns martial arts 3) The fighter who has sworn never to use violence again but is finally forced into it and 4) Martial artists from everywhere come to the tournament which is far more than just that. This actually adds a plot I haven't seen before in this genre. It's the good guy crosses the line plot. If you've ever watched an episode of Highlander the TV series this was a favorite plot there. The protagonist's character progression is amazing and unlike Western plot structure. He starts out as a jerk, then there is hope for him, yet he continues to be a jerk. Then you are cheering for him at the end because sometimes the world needs a jerk to kill the real villain.
The only thing I didn't like about the movie was the fights at the beginning. They are filmed in the dark and you can't see what's happening. With Kuan Tai Chen we need to see everything because he is the real deal. Fortunately the rest of the fights were showcases of his true skill level. Make this one an 8.0 for me. A note to all old school kung fu movie fans. I highly recommend Kuan Tai Chen's latest - "The Gallants" and rate that one an 8.0 also.
