I think its important to set expectations when watching this kdrama. Its not a sequel to the original bad guys but you will quickly figure out how they are related. It also doesn't really continue the idea which bad guys was about (bringing together a team of criminals to solve crimes). Its structured more closely to Chief Kim of all things. Essentially the drama has multiple arcs, each dealing with a boss related to the same corrupt scheme. It progresses pretty well but it can be kind of confusing. By episode 6 though things do become more clearer. There are some good twists in the drama and I was satisfied.

The original Bad Guys was more like a noir tv show that transcended the kdrama formula. This fall more in line with other crime, cop dramas.
