It's a villainess drama which we don't get to see a lot of. Knowing Kdrama, they generally give the same immature treatment for 99% of all villains ever. Even when we have a villain lead like this drama, they don't break the rule to have a better portrayal of a good villain character. Instead we get a silly dumbed down version of a baddie. You may as well add squeaky sound effects and air it on Sunday morning cartoons. To boil it down, you'll be watching 50-episodes of this king and concubine being clowns until they reach their demise because the drama ran out of episodes. I was hoping for a smart cunning play but we got a reckless uncalculated short-sighted arrogant one. Also, the drama had this habit of re-using the same evil tricks over and over instead of coming with something creative. Setting up the same traps is a case in point. On the bright side, Kim Hyun Joo was keeping the drama afloat.
