I am super loving it. It's light-hearted and not to be taken seriously. The action scenes are exaggerated but yeah it is comedy and if you can see the other work of the Pdnim (The Fiery Priest, you will see that it has the same touch of fun and excitement and antics!).
And the controversy, what controversy? I think people just want to make an excuse to bash this drama, but why?
I love both Ji Chang Wook and Kim Yoo Jung, they are nailing their characters, their acting is flawless and their chemistry is topnotch. They are THE BEST COMBINATION according to a recent Naver news.
