Bad Guys. Hm, the title says it all.. The best drama of 2014 for sure.. :D I'm thanking the writer, who done a pretty good job.. In this drama you will discover a world that most of us hate.. And how we react on those people. Somtimes justice is bi**h.. In this drama you have, Lee Jung Moon (Park Hae Jin), my favorite, who is the youngest serial killer and very smart person. They call him Psycho. Yeah, he is a bit strange in beginig but after when the action unfolds you will understand him. I even cried when he cried. I really liked that Psycho look on him. Then you have Jung Tae Soo (Jo Dong Hyeok) who is a contract killer, who suposed to be a profesional killer who does not feel guilt, but when he devolops feeling for a woman that he shouldn't love, he changes, a lot. Park Woong Cheo (Ma Dong Seok), well he is a gengster.. A hot looking gengster, with a warm heart, I like to call him Tank, because he solves everything with his might. I loved his bromance with Lee Jung Moon.. And Oh Goo Tak (Kim Sang Joong), who was a detective called Mad Dog, after death of his daughter he changed a lot.. The only goal in his life was to put the bastard who killed his daughter in jail. Everything in this drama is amazing. I loved the music, acting skills were great, fighting scenes were also great. Simple everything fits perfectly. I will definitely rewatch it. If you are not into action/mystery dramas than, you might not like this drama. But anyway give it a try. In the end you might love it.
