I am trying to be fair when writing about this drama. From the first episode to the last I just saw a bunch of men brawling: there was brawling in a building, brawling a another building , brawling in a hotel , brawling on the wharf brawling in an underground garage and yet more brawling. The story was the typical Korean corruption story, good guys make a step and then fall 3 steps behind. If you like this kind of drama then you will enjoy this.
Why I was disappointed?

The characters:
The first 'Bad Guys' hit me hard. It was different. The criminals were not just senseless persons that went around throwing their fists- 'me man lets see who fists is tougher' while beating their chest. They were intelligent.

The story:
I am not comparing this to the first Bad Guys but I would think that if I am making something of the idea of something else then I would at least make it have something of the original. The first was an original the second was made from a blueprint of every other Korean drama out there. The only thing that was missed was amnesia. (I guess that would have been too ridiculous) If the child have not characteristics of its parents then it was probably adopted.

If you want a good action show I would recommend watching Heartless City instead.
