This show is the return of Lee min ho korea's biggest star other than kim soo hyun, the show itself is really dull and slow. The idea of another world and stuff is okay but the way they deliver it is just cringe and not appealing to the audience. If you want to watch the show go ahead, it is quite cliché and the story is poorly developed. You have one of the biggest stars but this kind of fantasy with the kingdom stuff going between worlds is just simplistic and dull, If you are watching this for lee min ho go for it, if you want to watch a show that will keep you on your seat every episode and make you wanting more this is not the show.
