Brilliant. Genius. Beautiful. Heart-wrenching. Heart warming. Unforgettable. These are the words that are spinning in my head as I write this after just finishing the show. The potential was evident from the first episode and everyone delivered on the expectations that became exponentially high, even till the last minute of the show. There were moments when I wasn't sure how the story would move froward from that point or how they were thinking of executing a plot, but the writers wove the story so beautifully, everything just unfolds itself smoothly, it just wraps you up in a cocoon you never want to come out of. There was such warmth in the show, it's unbelievable. If you had to summarize the story of this show, it'd be pretty simple, could be done in a few lines. To have given a lifelong worth of depth to those few lines, to have brought alive the events in the life of the characters, to have made us feel what what the characters were going through with such beautiful narratives, the writers need to be commended. The plots could have easily gone awry in so many places, but EVERY plot, every character, every loose end - have all been taken care of with remarkable finesse. There are zero complaints or unsatisfied worms lingering in my head, none. Where do I begin with the actors? Where? I've been blown away, drowned, burned, buried, shocked - you name it - by every actor in this wonderful show. Ji Sung left me begging for more of him, even when he was present in 90% of the scenes, I just wanted more. "I wish that the time would stop, and that I could be with you forever", that's all that I felt every time he appeared. This guy can ACT, and he did a bloody brilliant job in this show. To have portrayed 7 personalities, is commendable. To have played 7 personalities with such absolute perfection, is downright worth worshiping him for. There wasn't a moment went he faltered in his performances, never a flaw, never a single crack in his portrayal. Be it the grumpy, violent, protective, dashing and charming Shin Se Gi; the middle-aged, goofy, bomb-making, beer-loving, accented Perry Park; the quite, calm, suicidal teen-genius Ahn Yo Sub; the foul-mouthed, oppa-crazy, troublemaker twin sister of Ahn Yo Sub, Ahn Yo Na; and the less frequently appearing 7-year old Nana, or Mysterious Mr. X; Ji Sung has lived and brought to life each of them. I didn't know it was even possible to be able to do such a thing! I had to literally pause the episodes and look at his face to believe in the changes. His eyes changed, how does one do that. Just with his expressions, his gaze, his very demeanor it was obvious as to which personality it was. He wasn't just Cha Do Hyun behaving like someone else, he WAS someone else. And it was one of the best performances by any actor that I've seen. My opinion of Ji Sung has reached the Sun. The lead lady Hwng Jung Eum came as a surprise to me. I've ever seen her works before and I'm glad I began with this show. She handled every scene so well. She was goofy and loud and cute and serious and mature and terrified and depressed - and every emotion was conveyed very nicely. I'm looking forward to seeing her other works. Park Seo Joon was a delight to watch, that guy made me laugh and cry with equal flare. His character was simply brilliant, very heart touching. It would be unfair to the others if I focused on a few actors more than the other but these three deserved the mentions, the rest of the cast did a pretty great job as well. They're the ones who were able to make the script, story and direction work. I don't know what I had in mind when I began the show, what it was that I had expected it would turn out to be, but whatever it was, it was nothing compared to what I actually got. The stories of each personality, their traits, the personality itself grows on you so much that it's hard to let them go. I found myself hoping for them to come out sometimes. I grew to love every facet, every broken piece of Cha Do Hyun. I was sobbing harder with every farewell. It felt as if you're losing a person rather than a personality. The story of each character in this show is going to be in my heart for a long, long time. I'm really glad I picked up this show, it is one of the best I have seen. The level of brilliance is more than worth watching. I'm already looking forward to rewatching it in the near future. I don't think I've had enough of the characters yet. The kind of show that Kill Me Heal Me is, you don't need any reasons to watch it, all you have to do it watch the first episode for a couple of minutes and you'll be irrevocably hooked, just as I was. It's everything you want in a drama of this genre. Everything and more. Don't miss out on this one, you'll be passing on a masterpiece.
