I like morally grey protagonists and I was really excited to see Lee Dong Wook take on this role, especially after his stellar performance in Strangers From Hell. The first few episodes didn't disappoint. The story of a corrupt (but not evil) detective being forced down a more righteous path by his own split personality was an original one. However, about halfway through the drama transitioned into a typical "main character uncovers mystery from his own past" type thing which has been done to death. A lot of things were also left unexplained. While I'm ok with having some things left ambiguous, you at least have to explain enough that the story makes sense. Unfortunately, especially in the last 2-3 episodes, there was a lot left out. So while the premise was interesting, the execution didn't live up to the potential of the story.

There were some positives: The acting was pretty good from all involved. There were a few funny moments. Great OST. I liked the more lighthearted tone of it.

Overall, this would probably make a pretty good weekend binge, provided you don't think too deeply about it. On the whole though, I have to say I was slightly let down by this drama.
