Story: very good ;
well written , comedy was smart while using very well the grotesque.

Soundtrack: very good ;
Not once i got bored by it, it helped the story perfectly.

Visuals: very good ;

Empathy to characters: very good;
It's not every drama these days that manage to get me attached to the characters.
In this one, i felt some attachment even for side characters.

Casting: very good ;
Everyone did well, but Shin Hye Sun stole the show, she is perfect.
P.S: Bae Jong Ok as queen dowager deserves an award.

Realisation + direction; very good ;

Pacing: Good

I'm not giving it 10, because i never give 10, but it came as close as possible.
I don't know why i waited so much to watch this.....
