I finally watched it! Was initially skeptical because it's 51 episodes but went ahead because of Ha Ji Won and Ji Chang Wook. And I m so happy I did because this is my next most favorite saeguk besides Six flying dragons. Love it! Story: it didn't feel like 51 episodes because the story can be divided into 3 parts i.e.before SN enters palace, in the palace then out then went back again. Both HJW and JCW' s character grew along the way. It has enough humor, touching moments , realistic power struggles ,comradeship and romance! I think this is one of those few saeguks that has so much romance and skinship. For me besides the struggle of empress ki , the other important story was the love that the emperor has for empress ki. Never once he deserts her despite many obstacles . Some people hate the ending but for me ,it was the best way to end- more realistic ,more impactful! Life is not always like a fairy tale . Casting/acting: one of the best cast I have come across besides SFD - everyone's acting was great. Besides the three main leads, the veteran actor El Temur , evil Tanashiri, Empress dowager, Tangqishi ,all were outstanding. JJM did not have much to do with his character but his acting touched me. HJW was beyond spectacular - from the innocent feisty Sungnyang to the cold seeking vengeance consort then the loving mother and wife left me longing for more . However JCW was a revelation for me in this drama. I have only watched him in healer prior to this but acting as this poignant yet devoted to love emperor made me fall in love with him! Watching him cries just make me wanna jump into the screen and hug him LOL. Music was good but as great as SFD Rewatched value: definitely a yes for me!
