I stumbled on this show on Tubi (US ad support, free streaming channel). I wasn't sure if it was going to be worth watching, but since it had generally high ratings and had Ma Dong Seok in it, I figured I'd give it a try. Boy was I positively surprised. This show, although it's definitely showing it's age a little, did not disappoint. I'd say the action is almost as good as Bloodhounds. The story keeps you guessing until the last few episodes and even though I wasn't sure how invested I could get in a crew made up of hardcore criminals, but their character arcs were written in a way that made them rather likeable. It was actually the female cop who was the most annoying. Anyway, it's only 11 episodes, very entertaining, with each episode ending in a cliff-hanger. Be prepared to binge-watch for a few hours.
