I dropped it after Episode 14 and I have to say that while this drama is really unpredictable at times, the overall setup and execution is predictable and cliche to the point were there's no point in watching anymore because you figure out quickly what they're trying to do and accomplish. But in turn, I've read the recaps for the few episodes remaining and while nothing surprised me, I'm glad it ended on a high note so this review isn't really the complete review but I've gone as far as I can with this drama. It started off loud and for the first little bit it was quite entertaining. Do Hyun's different personalities and the relationships within. A very unique and intriguing subject surrounding mental health. How the past shapes and molds our futures. JS has the best acting range in the industry. It takes someone special to pull off convincingly the variety of complex characters he was tasked to showcase. Everyone else played their parts accordingly. I will admit HJE's constant screaming was annoying but she had some great moments too. It is funny especially with the Perry Park and Yo-na scenes. The OST was okay, I was surprised by Gotye. The flashbacks really do hinder the story though for me. It's not crazy happenstance, it's fated crazy happenstance which is very tricky to achieve. I think the present time stories really suffered because of the over-reliance on flashbacks. KYR and OMS characters were severely underwritten and were non factors. If you told the story chronologically, would it have the same impact that it was supposed to or would it keep the viewer guessing enough to last the whole viewing without being told how to feel, I tend to go with the former. I also note that when this aired, there was another similar drama at the same time, Hyde, Jekyll, Me and I had seen and completed that before this one but I still consider KMHM the more serious of the two and overall much better executed story. So if HJM didn't do enough, KMHM does more than enough and some might say too much.
