Kill It is a dark intense Korean crime drama that discusses nature vs nurture, illegal organ harvesting, research ethics and medical ethics. The drama is about a professional killer (Kim Soo Hyun) who kills for money and is trying to find out about his past, and an ex-ballerina turned detective (Do Hyun Jin) who is trying to solve the mystery of the serial killings. Soo Hyun was adopted by an experienced professional killer for hire who taught him the profession, and has almost no memories from before he was adopted. I loved the story and finished the drama within two sittings. This drama had a lot of grey areas. Although he is a murderer, Soo Hyun is no where close to being evil, and at times I really felt bad for him. The cast was great. Jung Hae Kyun as Do Jae Hwan was great as the main villain, and I really hated his character. The music was good and fit the drama very well. If you are searching for a happy-go-lucky drama then this drama is definitely not for you. If you are searching for a drama with an amazing story that touched upon touchy subjects, and isn't afraid of watching dark and intense dramas then this drama is for you. Overall I would recommend this drama, and the ending made my eyes water.
