South Korea is a very different place than the United States or Canada, wich is where i live. Therefore everytime i watch a movie from there i am at first taken off a bit by how the peoples behave and speak, wich often look "cartoony" to me. I don't mean this with disrespect, its just stuff like "Big Brother" for older friends and overuse of bowing down kinda don't translate as well here.
But usually after 15 minutes or so i get used to it. This movie first start more as a comedy with a "Gary Sue" type of character, a way for the movie to justify the ass kicking that will follow without having to give him an overlong backstory.
Now i read the "Martial Arts Officer" concept really exist in South Korea, but i have no idea how realistic this movie actually is. I thought it was a bit hard to swallow at times how just 2 guys would go and would not call renforcements or such.
Ultimately the movie want to be a Martial Arts action flick, and this is where it shine. There is plenty of fights, they are well done and brutal.
And finally the movie explore also some very dark territories wich kinda contrast the more comedy elements. I guess its another SK thing cause its not the first time i seen this.
So is the movie perfect? No. But its a solid action/fight movie that should entertain fans of the genre, and there was a few scenes wich did made me squeeze my knuckles if you understand what i mean, so i think it did its job on what it aimed to do. Had an overall good time.
