The only flaws I found in this drama were the following... 1) the flashbacks. OMG SO. MANY. FLASHBACKS. I ended up skipping ahead often during last few episodes but I think it didn't detract from my experience as an audience. *happy face* 2) The female lead's screaming tendencies. My friend thought she was comedy gold and loved her hilarious screams, but it personally hurt my ears. I had to turn down the volume every time she looked like she was about to yell or shout---SHE IS HILARIOUS THOUGH I ADMIT. 3) The long kisses. ... Honestly, they just need to kiss already. THEY SPENT 30 SECONDS STARING AT EACH OTHER BEFORE FINALLY TOUCHING LIPS. Wth? But anyways, that's the editor's fault. The male lead Cha Do Hyun is actually an AMAZING kisser---I blushed several times during this drama. kekeke. 4) Episodes 16--20. Let me explain: the first half of the drama were mostly comedy with some sadness hiding behind it, but the melodrama poured through starting in ep. 16. It was lined with sadness after sadness, and I literally cried until I just couldn't shed tears anymore. LUCKILY, there are still quite a bit of comedy relief in those 4 episodes---so I was able to survive and come to love it. But despite the flaws of Kill Me Heal Me, I loved it for it's sensitivity to D.I.D., and for its array of top notched actors who slayed the drama. *v* Ji Sung is absolutely amazing in this drama. According to what ppl have said, HE ONLY SLEPT ONE TO TWO HOURS to film this. That's true dedication. Also, you have to understand that it's very hard to portray 7 different characters, but Ji Sung managed to nail the role. The female lead was also amazing. Everybody was amazing, tbh. I personally loved the melodrama in the end because it was realistic. DID is not meant to be funny. Childhood tragedies are also not meant to be glossed over. I'm glad this drama actually took the time to show how horrible both things are--That alone gives this drama a high score.
