Five minutes ago, I watched the last episode of this drama. IT. WAS. GENIUS. The plot was very interesting. But it wasn't how I expected it to be, it was better. What I love the most about this drama, is that, it was very unpredictable. And, it has everything. The script was very mature. I really loved it. It wasn't cheesy and it didn't ruin the scenes, it made it better. Nothing was too much. I loved the fact that each episode has something new, there wasn't ever an empty episode like regular dramas. I'm also very impressed with the gradation of how Cha Do Hyun's memory return. In other dramas, they just keep dragging the episodes and then everything is revealed in the final episode. But, in "Kill me, Heal me" his memories return gradually which was believable and realistic, and it gave us something new in each episode. I loved every personality Cha Do Hyun had. Every single one, specially Shin Se Gi. I routed for him from the beginning. I loved them more after knowing the stories behind them. The plot twists were just... wow.. amazing.. amusing.. shocking.. everything I've ever dreamed of in a plot twist. Again, nothing was predictable. You think you figured everything out, but then suddenly the writers drive you insane. The acting was epic. very real, and the face expressions were suitable. The supporting roles did a great job. I specially love the brother, Oh Ri On. The music was good. It wasn't fantastic. except for the song "Auditory Hallucination" which was brilliant. I want to re-watch this drama, I think I will, sometime in the future. This is a definitely watch drama. It was funny, genius, heart-warming, thrilling and just.. Genius. It's on the top of my recommendation list!
