I never wanted to watch this when it first came out simply because i foolishly didn't like the glasses image of Hyun Bin. Just recently I became curious and turned out their ratings flopped so bad for a drama with such casts. Probably because of the bad reviews and low ratings, I was intrigued, started watching with very low expectation and ended up finding myself hooked to the drama. There are some parts which were a bit draggy, but it was actually a well-written drama. The way the writer actually put emphasis on both Hyde and Jekyll characters, and managed to slowly integrate them was indeed applaudable. It was psychologically interesting. I have seen people commenting that some scenes are illogical but if you look closer, those scenes depicted real life situations for a fact that human mind is complex and each one of us manifests pain differently
