I will say this script had a very good balance: There was funny moments, emotional and thought inducing scenes, fight scenes and some light romantic scenes.
How the screenwriters managed to tell the rather tragic life of Joseon widows without it adding a heavy emotional feel to the series was well executed.

It was a refreshing take on a historical drama, with unconventional female protagonist.
As for the FL, I liked her in One the Woman, and she gives a good performance here as well; she suits this kind of role where she can utilise her comedic timing.
Kim Mi Kyung (her mother in law) was brilliant as always.
