Honestly, I don't think this show deserved as much hate as it has received on here. I've been on a Hyun Bin run the last few weeks, and was reluctant to watch this because of all the bad reviews. I was expecting a total disaster that I was going to give up on in the first few episodes. But as I watched I kept waiting for it to take a nose-dive and it didn't ever really do that. That being said, just because it didn't fall to low expectations, it didn't rise up and "wow" me either.

Now, Hyun Bin's acting, as I've discovered is very good. He plays double roles very well, making it believable he is different characters. He did basically the same in Secret Garden. (I really wish he'd choose some better roles so I can see him in something worthy of his skills.) This was the first real role I've seen Han Ji Min in (other than her Jealousy Incarnate cameo), and she did an okay job. There was something I liked about her.. Sung Joon can be hit or miss for me, but I actually liked him in this even though the character could have been scripted better. Hye Ri was cute, but fairly unnecessary in this show.

My main gripe with this story was the amount of time that Hyun Bin spent as Robin compared to his time as Seo Jin. Yes, Robin was heroic and happy and nice, while Seo Jin was...well his polar opposite. Yes, they are both different sides of the same person, even if Hyun Bin did an amazing job at making you feel like they were two separate men, not sharing one body. I would have liked to have had more time with Seo Jin and Ha Na interacting and getting to the bottom of his illness. I felt really sorry for Seo Jin and how he was treated compared to Robin. I did like the way that Ha Na's interaction with them "both" helped Seo Jin through his past and work through Robin to heal him. I just wish I had gotten to see more of his change through HIS eyes, and also that they had resolved the problem of Robin earlier in order that Ha Na and Seo Jin AS Seo Jin could have had more screen time together getting closer. And maybe that's the crux of what didn't work for a lot of people. Even though Seo Jin and Robin were the same man, it would have been nice to have seen more of the REAL man, Seo Jin as opposed to his alter, Robin - who was just a "symptom" of his DID.

The music was fairly good, enjoyable and appropriate.

I don't see me watching this again, but it really wasn't as horrible as so many reviewers make it out to be. There just wasn't enough of what I wanted to see...it was crammed in at the very last few minutes so I felt a bit cheated somehow (even though they were the same person).
