I know alot of people probably won't agree with my rating  but despite this, I decided to justify my rating choice. I normally don't because who even cares, but the more I thought about this drama after I had finished it, the more disappointed in it I got. While I liked it, here's my rationale behind why it's not the best out there or the greatest.

story: While the story was interesting and unique, I felt like it was ultimately directionless.  I loved the supernatural theme, and I believe that is what initially piqued everyone's interest in the beginning. Well, that and Lee Jong Suk of course ;) However, the more the story drug on, the more I felt like the supernatural unique aspects of the drama began to disappear and lose it's "magic" and appeal. It just became redundant and somewhat lackluster. In the end, the story tied up nice enough but I'm still left a little deflated with a lingering feeling that it could have potentially been more.

characters:  In the end, the characters and character development, or lack of I should say, was what disappointed me the most. Lee Jong Suk did a marvelous job with his character. I could see his growth from an immature troubled youth still struggling with deciding between right and wrong and later watched him grow into a young man who stood firm in his beliefs. It was a seamless transition and I enjoyed the progress. In comparison, Suzy's character barely had any character growth. Her character was one dimensional at most. It was flat and a little boring to be honest. I don't know why, but something about her acting never communicated to me or pulled me into the story. I had the same problem with our second male lead in question, Han Woo Tak. While a handsome specimen and a potentially intriguing character, I felt like he was even more tasteless and boring than even Suzy. Even worse, I was left hanging till the very end wondering what dirty little secrets he was hiding or quietly pondering the possibility that Woo Tak might be more sinister then he let on as some of the directing of this series seemed to insinuate. I was sorely disappointed however when his character and role in general just fell flat resulting in a character I strongly felt was ultimately pointless and boring with no real character development either. I sometimes felt the side characters at the law firm had more interesting interactions and character growth to be honest.

music: The music in this was superb. It fit the scenes perfectly and was able to pull the perfect emotion for every scene. It was as beautiful as the cinematography which I also happened to find beautiful and breathtaking.

Chemistry: The couple chemistry was only so-so. I didn't really feel much of a connection between the two actors and I continue to feel like their relationship bordered on closer to friendship then it ever did to an actual intimate relationship.

Antagonist: And finally, the biggest problem I had with this entire drama was the antagonist. It was almost comical how the painted a big red villain sign on Lee Yu Beom. Sure the dude was crooked and manipulative but as the series drew on, I expected a little bit of insight into his sinister mask. What made him tick? What was his backstory? Why was he so twisted inside? They had so many opportunities to draw forth various complicated emotions from the viewers with a more complicated and complex antagonist so I was sorely disappointed when they decided to paint everything black and white and simply made Lee Yu Beom into the typical "Born to be the bad guy" lead in which every action he has ever taken was meant to cause distress to our main heros. The struggle between the antagonist and the protagonist was much too disney version for my liking. Character depth is more realistic and has the potential to leave a more lasting impression on the audience.

With that in mind, I over all rather enjoyed this series. I'm not dissuading anyone from watching this, if you are considering watching it then by all means go ahead. It was an enjoyable ride and I don't regret watching it. I would say it was worth the watch. If you are looking for something rich in supernatural mystery or character depth then I would advise against it. This drama was more focused on things like standing firm in your beliefs, distinguishing between right and wrong, human connections, and how we are all ultimately tied together somehow in an intricate and dynamic web of fate.
