To be honest, this is the first Sageuk with 51 episodes that I have watched and like some other viewers, I was hesitating to do so too. I usually keep it to mini-series. But after hearing a lot of praises for the main leads, especially Ji Chang Wook, I decided to start Empress Ki on a "Now or Never" basis. And believe me, I don't regret it. The story at first seemed like a normal love triangle but the development of characters was really nice. I know, this is a fictional plot of Empress Ki's lifestory and I don't think its written that worse. The cleverness of the writers about Ha Ji Won's character is just fantastic and the political plot of the drama is not too bad, by putting in the betrayal/non-betrayal portion a lot. Acting and Cast, as everyone applauds loudly to, was amazing and I actually had to give Ji Chang Wook's character and acting a bow when I finished the whole series (Last Episode, blew me off. It was so over the edge emotional and touching, that I was crying the whole midnight!). Actually, I also appreciated the acting by Baek Jin Hee. Though, I loved to hate Jung Woong In's character ( his acting in "I Hear Your Voice" has still not washed down on me yet ). I loved the Original Soundtrack too, and I was just in the mood for some Historical themed genre (second reason why I gave this drama a "never turn back" go!). Re-watch Value is 3 for me because all the plot's been revealed and the curtains have been lifted off the suspense now and maybe because re-watching 51 episodes again will wipe out my Internet bytes, but I do watch some clips that I miss from the drama and believe me, such clips are many!! Also, if I stumble upon it years and years later, probably when I'll forget the plot almost completely and I'll have unlimited Internet bytes, I'd definitely watch it again. Overall, it was a good drama and I'm missing it as much as I'm happy I watched it and not just let it be there sitting on my Plan To Watch List. Enjoy! :)
