I have no complaints about this drama. Even if there was a slight wrong in the whole drama, I didn't notice it because the acting, the story the scenes were soooo good.

I absolutely go bonkers for historical Kdramas and this was one of it.
Jang hui bin especially was played to perfection, the badest bad. A proper villian who took all the advantages against her protagonist. the humor to the story now and then. The wonderful depiction of Crown Princes Suning and Yeoning (Gyeongjong and Yeongjo) loved it!!!
You'd have missed a whole world of fun if don't watch it!
