I have created an account for the purpose of writing a review for this series, I haven't a clue, how this sorry excuse of an adaptation has a rating above 8. It is my sincere request to each and every one of you to go and read the Web Novel or for an even better experience, the Webtoon adaptation of the Webnovel, the author of the series and the characters he has written deserve better and I will explain why.

1. The Plot : The problem with the plot is that, in the novel, the MC dies and goes back in time as the son on the Chairman's estranged but his own son he has with his wife. In the drama, since it would be difficult to view the character as someone else, it is made so that this particular grandson had the same face which is Song Joong-ki. The ending is even more disastrous, it is a thorough insult to the author of the Webnovel.

2. Characters: Lee Sung-min as Jin Yang-cheol was perfect, his acting skills had me in awe, but the entire characters, regardless of the casting were no where near as deep as the original work. Jin Yang-cheol is a complete sociopath, he is an indomitable wall, the wall that has defended Soonyang and the general that spear headed it's growth, he is not a vulnerable person and his ability to think rationally and stay calm is what makes him a truly scary character, the essence of Jin Yang-cheol who I would argue is more important to the series than the MC was lost, he was a broken old man in the series. Jin Yang-cheol is feared by his children because they know he would rather take Soonyang to his grave than give it to his children, he wants them to steal it from him, yes 'steal' is the right word and that is how much of a sociopath he is.

The MC is actually a lot smarter, he does not get out maneuvered, he is always steps ahead of his enemies, to make the series feel like a thriller, unnecessary twists and turns were added. The characters in the original work have a deeper story and better development, they don't want Soonyang just because they think "I should be the rightful heir", it gets a lot more complex than that. The original work also has romance, they removed a good portion of it.

I do not claim to be an expert on K-Dramas, but this series, is a complete bastardization of the original work, the author and his hard work has been insulted in my opinion, I could write a lot more, but the more I write the angrier I get. I have nothing but absolute pity and contempt for those who gave this pathetic adaptation anything above a 2 star rating. I implore my fellow audience to look beyond the cast while deciding to rate a series.
