Is Gong Hyo-jin's drama any good?

It seems to be based on a webtoon called "Married Woman Killer"... I haven't watched it because of the controversy surrounding the male lead, but I saw that it got around 9-10% viewership ratings.
I was worried about Gong Hyo-jin since her drama with Lee Min-ho was a huge flop, but it looks like she at least did okay this time.
