I am not a fan of costume drama/movie and have limited knowledge of the truth historical events which the story is based upon. I even have doubt of watching this movie at the first place. But the slogan drew me in, 'The Kingdom in the hands of a layman for 15 days".
The front part for about 30 minutes is kind of pale. But I am happy that I got through that. Because what follows is the one of the most intriguing and interesting plot I had watch for a long time.
It is simple plot. A king is afraid of an assassination plan (later got drugged) and proceed to hide himself and put a fake on the throne for 15 days. The story follow Ha-seon, a layman impersonate as the fake king puppet during his 15 days reign of Joseon Kingdom and the relationship with his servants and the queen.
Lee Byung Hun is terrific as King Gwanghae and Ha-seon. The transition through and forth is clearly display. The affection towards his maid, Sawal, the Queen and the royal chief secretary is so well acted.
This movie give people something to think about. A king and a layman is not much different. A king is made to rule the country but he is not necessary the best man for the job. In the other way round, a layman with little literature education who had experience the poverty and difficulties as a citizen should not have the ability to rule a kingdom. BUT, HE DOES WITH HIS OWN WAYS AND MADE CHANGES THAT TURN THE KINGDOM INTO A BETTER PLACE.
