I've known that Kill Me, Heal Me is considered one of the best mainstream K-dramas, so I've always known that I had to eventually get around to it, even if the plot didn't interest me too much. What got me motivated to watch is seeing Ji Sung's impeccable acting in Doctor John - I just needed to see him in something else. So I finally gave Kill Me, Heal Me a shot.

Ji Sung did not disappoint. He portrayed each personality exceptionally well with true, solid distinctions that made it obvious who he was in a believable way.
Hwang Jung Eum was surprisingly good and Park Seo Joon was a fun plus to the story.
Acting was overall enjoyable and actors in general were well cast.

In regards to the plot, I wasn't too impressed. I didn't dislike the drama, but there were some loose ends that weren't thoroughly resolved in the end and some of the plot devices are a bit overused in the K-drama world of today and therefore, unbelievable/predictable, lacking the impact they were meant to inflict.

What kind of fell flat to me was the ending. I think that the bad guys were written pretty black-and-white for the first 3/4 of the story and then in the last 2 or 3 episodes they are all of a sudden more complex beings and not all bad. This didn't flow well to me because the shift was very abrupt and inconsistent with the rest of the drama.

I think something else that was lacking from the ending was the relationship resolution between Do Hyun and his first cousin. It was implied that they would eventually have a big scene together fighting or whatnot, but it never happened, which left me wanting for something more. It was implied that they had a close relationship as children and that it needed to be mended as adults, but they barely had any scenes together throughout the whole drama. Which brings me to wonder, was it really necessary to include the cousin as a "villain" who was relatively harmless compared to the bigger demons Do Hyun was coming to terms with?

On the plus side, this drama had WAY more birth secrets than I thought it would AND I was genuinely surprised twice, which is a good thing. XD

Anyways, Kill Me, Heal Me is a decent drama and I understand how it became such a huge mainstream drama, but it personally lacks that extra umph that gets me to weep and rejoice with the characters. Honestly, I think that this drama gets all the attention as being a "must-see" because it's one of the few that deals with mental illness as the main plot device, which is good, don't get me wrong (mental illness is definitely under-represented in media and *should* be recognized), but just because the drama is addressing a minority concept doesn't mean that it's automatically amazing.

Kill Me, Heal Me has flaws, just like every drama, and for me personally, the great moments of this drama did not outweigh it's shortcomings for me to glaze over the flaws. What kept me watching was Shin Se Gi (he was my favorite character) and the small comedic moments sprinkled throughout (especially through Ahn Yo Na). And for those of you who are wondering if this is a romantic comedy - I wouldn't consider this a romantic comedy. It is much more of a melodrama - there's a lot of well-deserved crying and emotional outbursts in the second half of this drama that shifts the genre significantly to me.

Oh! And I would really like to add that while Hallucination the OST is AMAZING, the instrumental piece that sounds like a circus' theme song is TERRIFYING and every time it came on, I desperately hoped that it would shut off. XD
