The cliche revenge plot made me avoid it at first but DAYUM am I glad that I chose to watch it. Some twists may be predictable but lord the acting, the pacing, the directing and cinematography made it all so worth it. At only 8 episodes, it's perfectly paced for a thriller, no scene is wasted. Park Hee Soon absolutely owned his role as Choi Mujin, I hope he does more gangster roles in future, the costuming suits him so well. and now I cannot stop rewatching!!
