Yes! I was waiting so long for a movie like this from the Korean ground!
This movie sucked me in after one solid minute and liked it to the last. It made me think of movies from Donny Yen and Iko Uwais. There are too few of them and Bruce Khan delivered it for Korea.

The story: Allright, this was the only thing that was kind off lacking. We all know this setting too well (for me it works) but something else would have been nice. Also I had trouble liking the child-actress, her acting was good but the character dislikeable. One moment she appeared younger, than older, she was messy and than clean etc.
I do think that this movie could be +1 hour longer with a good story from their flashbacks, it would made this movie a whole bunch better.
But, I loved the way they directed this movie. I can see the efford they put in, trying to make one scene cuts and filming from different perspectives it gave me 100% flashbacks from the movie form Uko Uwais: Raid 1 & 2.

The acting/cast: Well I'm going to fill this part in only about Bruce Khan. He did an splendid job, having only 5 lines throughout the movie, he still managed to be understandable. Do not forget, this Bruce is 50 years old and managed to nail every form of differend forms martial arts, judo, boxing, sword fighting etc. I think that is honorable and amazing! I 100% believe that we are going to see him much more on screen, he deserves it.

The music was fitting and I would 100% rewatch this movie, solely because I love these kinds of movies.

Watch this: If you like mixed martial arts movies and if you are okay with not such an indepth storyline.
Skip this: if you can't handle blood, there is alot.
