I wish I could say I was enthralled with this series like so many others but something kept me from falling in love with it. One of the main reasons was not being able to understand every single business/political element to the story and there is plenty of it which is what adds to the thrill. So if you cannot completely comprehend some of those "wins", it gives a very dull effect. Something the writers should have considered and tried to explain or simplify. You can still enjoy the show. Just not to the full effect.

Best moments:
1. There are many shocking moments and revelations that you can't anticipate and were enjoyable.
2. The fantasy element that adds a twist and is a major part of the story.
3. The relationship between Do Jun and his grandfather were truly some of the best moments.
4. The way Do Jun makes his way through the hurdles armed with the knowledge of his past life.
5. Seeing the Jin family fail and fight amongst themselves was amusing.

Not so great moments:
1. No one noticing that Yoon Hyun Woo and Jin Do Jun look EXACTLY alike.
2. Not being able to understand some of the "lingo" fully.
3. Do Jin ignoring his family after his real mother's death even when he could have.
4. The romance is practically non-existent and although I would not care otherwise, it feels like they built up a story for no reason.
5. The conclusion. Part of it does not make sense. You are rooting for a character and in the end, everything feels a bit bland and unsatisfactory.

Up until the 14th episode my rating was 8.5 for this show. I'm changing that now to a 7.5 based on the last episode. I am not likely to rewatch this show but it's a decent show. There are plenty of good reasons to watch it.
