I will mention BOTH the good and the bad of this show----- SO THIS IS KIND OF LONG, SORRY. THIS SHOW IS HONESTLY AT THE LEVEL OF MASTER'S SUN, YWCFTS, AND HEALER. It is one of the best so far for 2015. At a first glance, this show may seem like a mess. When I began watching this show I had VERY low expectations because of the description -- rich chaebol with memory lapses and 7 different personalities falling in love with a docto......... it sounded like a recipe for disaster. But, don't worry because the writing and production team turned KMHM into a masterpiece with the help of main actor Ji Sung. ALSO, the title Kill Me, Heal Me is beautifully illustrated in the show--I cried tears of happiness when I saw the meaning. Not only is the show itself well-written, it is CONSISTENTLY GOOD. Where many other dramas slowly fall apart half-way through the series, this show managed to keep delivering quality episodes from start to finish. the actors also flesh out their characters and fill the show with meaningful symbolism. ACTING: Ji Sung is, hands down, the BEST ACTOR I have ever seen in a Korean drama. (My opinion only--pls don't be offended) He makes me laugh with him and then immediately cry a few seconds later. If that isn't superb acting ability, I don't know what is. The screen romantic chemistry between the two leads are also OFF THE CHARTS. They are amazing together because this is the 2nd time they've acted together! :-) Anyhow, I have only praise for the acting in this drama. MUSIC: 1/3 of the reason why I cry every episode is the music. The main OST, Auditory Hallucination, is a perfect mixture of rap and soft singing, and this contrast between soft and rough reminds me of the doctor's healing and the main character's tragic anger. After watching the first two episodes, I've been listening to this song every single day for the past 2 months. In fact, tears are rolling as I write this--I'm listening to it right now. The other songs are also perfectly timed, although they didn't leave as heavy of an impact on me. PLOT: Multiple-personality disorder is a sensitive and controversial issue that can easily be misrepresented or shown with a lack of seriousness. KMHM manages to avoid this problem despite its hilarity. The plot successfully transitions from comedy to tragedy in mere seconds, and this is the reason for its success: by having light comedy first, it then forces us to look at the sad situation of personality disorders without us looking away. Many people, including me, dislike pure melodrama--and KMHM did a great job of softening the blow while maintaining its seriousness. I promise you there ARE hilarious situations every episode, but overall the show leaves you wondering about what the main character had to go through in his life. This show makes us feel pity for the characters without using cheap tricks. An evidence of this show's success would be when fans of this show fundraised over $3000 in a week (american dollars) for a cause after watching the show. REWATCH: YES YES YES. I personally watched this 2 times before writing a review. I plan on watching it again in a couple of months. NOW, time for my CRITICISMS: - One thing this show overdid was its flashbacks. This can get a bit annoying after 14 episodes, so make sure to skip ahead if you ever get tired of it. (skipping some flashbacks will help you have a good experience with this drama) - The main female lead's high pitched screaming can be very loud and irritating---especially for people with sensitive ears. Be careful with the volume control, guys and girls. I personally got used to it, but I know some people who couldn't stand her voice.
