Actually i didn't want to watch Empress Ki, because of the ending but somehow i  endet up watching it.
From the 1st to the last episode i was so into it that i skipped sleeping and eating.
It's rare for me to fell like that for a drama, it's the second after "Girl in Blue"
The actors were great, the plot was close to history but i was a little bit dissapointed with the ending.
They should have left it open or made it like history says.
No matter what it's a drama i will never forget and rewatch for sure.
