I really just don't understand the hype for this. I just could not get into this at all. I was so excited to watch it once I found out it had to do with DID (dissociative identity disorder) as well as after hearing all the rave reviews, but I couldn't be anymore let down. My biggest issue is with the portrayal of the illness (DID) I know this is a k-drama so I didn't expect textbook accuracy with a mental health consultant on site during filming or anything like that, but the portrayal of DID is just so silly and flat out stupid that it completely removes any empathy I felt for Do Hyun's illness. When he switches personalities, it's much more akin to a comic book villain transforming than it is someone changing personalities due to mental illness. I could stand for the corny eye color/tattoo change thing if that was my only issue, but add to that the seizure like tantrums he experiences when he switches on top of that and I just have checked out at this point. Despite my faults with the portrayal of the illness, there was some interesting plot lines here, but they were all so convoluted and muddled to the point that I hardly ever knew what was going on. I've never been one for bureaucratic/corporate espionage and conspiracy plot lines, but the ones here were just so exceptionally dull. It was way too much, all the different family dramas, the corporate theatrics, the mental illness, murder mysteries, all kind of thrown together into one incomprehensible mess. I really wish this had focused much more on Do Hyun staying inpatient while battling his illness and trying to recover his memory, while also dealing with the blossoming relationship between himself and his doctor (the female lead) I had a lot of issues with the tone as well. It's kind of all over the place, and I love a lot of drama sthat transcend genres. This just comes off more as desperate and unfocused rather than creative and eclectic. I also found this show to be quite ugly to look at as well. Just very dry and washed out looking... I don't know. I don't mean to rag on this drama too much as I can understand why some people would enjoy it but there's just too much going on for me.  There is a great show buried deep down somewhere in this mess. I just wish I cared enough to dig and find out.
