Apparently I´m one of the people now that start with: I´ve never had the urge to write a review but this show had me glued to the screen which surprised me after reading the reviews on this site.
I read that The King´s Affection dragged the story, started well but lost it´s tension along the way.
For me this is one of the most interesting historical dramas I´ve seen so far (which are a lot :-)) I´m a sucker for romance and a lot of the political scenes drag for me in most of these dramas. Don´t get me wrong, I think they´re an essential part of this genre and when executed well I don´t get tired of them. This was the case in this drama. The mixture between romance and politics, friendship and intrigues, laughter and tears was perfect for me.
I had characters I loved, others I hated and others where I just shouted at my TV because they were annoying and thoughtless.
The story kept me engaged, I was always wondering what would happen next and also how people were gonna react to certain realizations.
I couldn´t help but root for the characters, the villain was worthy of that position. The heros proved that it´s possible to choose the right path over and over again, even if it´s the hard path.
The ending was satisfactory, I couldn´t stop smiling. The only thing I don´t like about the ending is that the new king didn´t get a happy ending. Loosing the closest people to him seems to bring him to lead a very lonely life. He deserves better.
So here you have it, my very first, probably not very stringent, review.

In short: Def a recommendation
