I assume that you have already watched the whole series, and this review is meant to discuss one problem of this overall very good show. So if you are looking for a thorough review of the different aspects of this show. This is not it. I mainly want to discuss one thing, namely, the the plot design of the very last episode. So let me explain my major issue with the show, and proceed to offer short comments on other aspects of it.

The major issue has to do with the overall themes of the show. It is worth saying again that this is an overall very good show. The majority of the plots are nicely laid out, and delivered to the audience in a digestable pace. This is not a show where the plots get so complicated that you need to re-watch in order to understand some of the intricacies. This is not to say that the plot is very straightforward and banal either. Both the premise of the show (namely, the a clown all of a sudden becomes a king) and the overall story progress are interesting and not cliché. The major conflict through the whole series, namely, the political and power fight within the court, is complex, multifarious yet well-articulated such that the show never gets boring (for me).

Spoiler alert again:
The major problem I had with this show then is where the show should end (I know, pretty technical and even pitty). The time distribution of the last episode is wrong. Given that the major conflict is the political fight, the show should end shortly after where that major plot is finished. While there are other themes and plotlines, such as the romance between the King and the Queen (roughly), the main theme is not romance, at least not so for the 15 episodes of the show. However, at the very end of the last episode, the director spent 20 minutes of the episode on romance, which has nothing to do with the political fight (because it is already finished at this point). It is also not very good romance: 20 minutes about how the King and the Queen are not able to find each other has "tears" value, but feels highly unnecessary. This last bit of the show, therefore, negatively impacted the overall coherence of the show because that bit, which is used to conclude the whole show, makes the whole show look like a romance when it is not. If someone only watches the last episode, s/he would have wrongly thought that romance is a major theme of the show. If s/he gets hooked by the last episode and decides to watch what happens before the last episode, s/he would be disappointed. It is as if the last episode is a nice bowl of chicken noodle soup. If someone likes the chicken noodle soup and wants more of it, s/he would be disappointed because the first 15 episodes are not chicken noodle soup, but stir-fried chicken and noodle with a bit of sauce. This is my major complaint of the last episode: still nice on its own, but not a good episode for concluding the show.

A minor complaint is the sound track, esp. the use of Schubert's ständchen, which is the theme song for (most if not )all romantic interactions. The melancholy of the song just doesn't fit well with some of the sweet interactions.

Actors are good! This is my first time watching the female lead Lee Se Young, and she catches my attention.

Much more can be said about the show, but I don't have much more interesting to add on top of all the reviews. So let this be it.

Thanks for reading.
