Gah! What a stomach churner of a show. In all good ways. The acting and the story brilliantly executed. The show keeps you guessing who the ultimate antagonist is. The characters were so well fleshed out that you end up rooting for the seemingly bad guys. The show manages to turn tables on what you think is good and evil which makes me tip my hat to the writer. Having said that, I do think the show has a glaring flaw...Soo min. Why. Just why. Her character just seemed irrational and entitled. And that is being compared to drug lords in the drama! While everyone else in the drama, from drug mafia goons to the police were earning their keep...was conscious of the cost that has to paid for every action they take, Soo Min just seemed to take it all for granted. Which made the entire romance angle seem shallow but considering its a drama you can take that leap of faith. Soo Min as a character didnt overpower the brilliance of the show but it kept nagging me everytime the character appeared. I dont if the aim of the writer was to make the audience dislike her or root for her. If she was intended to be disliked, then brilliantly done. If not, then she can be slightly redeemed for being a naive untrained cop. And kudos to Madam Lee and Doctor's son. Such amazing characters! They totally managed to win me over everytime I thought Soo Min didnt make any sense. Their relationship is so weird yet so enviable. And thats what makes it so fantastic. They have their moments of doubt but never at the cost of each other. The true strength of their relationship is that one moment in the last episode. Oh the tears I shed. I hated the villians with passion and I loved the heros and antiheros with passion. And that makes the drama golden in its own right. It manages to hit all the right spots in your heart.
