Jang Hyuk utterly and undeniably stole the show.
His character, counselor Park, was so profoundly well-written that I am having difficulty hating his character, even as a villain. He had layers upon layers… Even his layers had layers. One of the best-written villain’s characters that I have ever watched since the character of Yi Bang Won from “Empire of Lust.”

Kang Han Na was unapologetically superb in her role as Yoo Jung/Lady Park.
Her character personified that old saying…
“If she was a man, what a King she would have made…” She had all of the necessary and all of the sort-after attributes of a great King. Again, one of the best-written Queen’s characters that I have ever watched since the character of Queen Im Hwa Ryung from “Under the Queen's Umbrella.”

Lastly, Lee Joon…
What What can I say about his role as king, Lee Tae…?
I do feel bad for the actor. Any actor placed in a scene next to Jang Hyuk, whether it is a first male lead role or a second male lead role, is going to look unfinished and less skilled. Then, we have the writing behind his character… While his 2 costars’ characters writings were profound, well-written and full of layers, the writing behind his character felt weak, untrustworthy and incomplete. Throughout the entire 16 episodes, I really didn’t see any growth in his character. His character remained abundantly emotional, vengeful and neurotic at times.

All and all…
One of the best Sageuks that I have watched from Jang Hyuk and I am utterly impressed by Kang Han Na‘s acting prowess.
