I’m not that far in, but this is a pretty decent show.
It’s basically Game of Thrones for the Korean audience. It takes a while to figure out the characters and some of the culture differences are a little odd to figure out but it’s so far pretty well plotted. The acting is good for a Korean show - which relies on *gasp* reaction shots more than American fare.
What I like about it is that - like Game of Thrones - it’s not always easy to figure out who the bad guys are.
Problem is it’s 18 episodes. Each way over an hour. I may get to the end but it’ll be a while.
