Lets start of that i had no clue about the cast in Cruel City and it is aired on a Cable broadcast channel JTCB which i clearly never heared of,Anyway i read storys from people with exiting thoughts about this series so i gave it a try. This Story is a really Thick one with many layers,In the start of the drama i had To be honest no clue what was goin on and couldnt find myself to love any characters yet inside,However after the 2nd and 3rd episode kicked in i started to notice how deep this drama actually is.This story evolves around "Drugdealers" that seem to be so deep inside it that they end murdering up each other for whoever dont make the deals correctly.The Tital "CRUEL" Means cruel since people are hitting each other with GOLFCLUBS And Iron Maces.People getting most of the time brutally murdered bcuz they made errors and getting slaugtered by the people above them(The higher ups). The guy in the police department is trying to get revenge on those druggdealers since his younger brother lost basicly his life on druggs and is now hospitalized.Then you got this other dude called Doctor's Son which is an "Undercover agent" for the police which is himself involved into the drug buisness and by doin that he is trying to capture the bad ones "the higher ups". The story will evolve bigger and bigger and is one big mystery since the police will try to capture Doctor's Son for certain reasons and Doctor's Son is trying to stay alive since he is an undercover and need to accomplish his mission to become a police again.Then you got the Higher ups which are in command of all this and have the power over everything which makes the Police completely Useless to accomplish what they actually want too. I can go on about this for ages but i cant "spoil" more of the story,there is so much happening wich so much meaning behind it that this drama is certainly 1 of the dramas with the biggest story ever.Only funny part is that THE "KNIFES AND KILLER WEAPONS" Are CENCORED.This is completely new for me and never saw something like that but im not really bothered by it but its kinda funny. The music in this drama is kinda dark and if its running in the end of the episode it gives you some sort of a thrilling feeling.However it does get repetitive at times and there could have been a bit more variation to that. The ending in this drama is really open ended and leaves you with some thoughts in your head. Conclusion: A super good K-Drama with allot of Suspensive and twists in the story,Its definately a must watch!,I think story wise you wont find anything more deeper and dark than this one however dont expect to see happy tea times in this drama bcuz its really as the name says "CRUEL CITY".
