This drama had potential to be good considering its parallel universe plot line featuring doppelgangers. It became quiet clear however that all that potential was thrown out the window as the drama focused heavily on a forced love line between the Prince and Lieutenant. The Prince barely knows anything about the Lieutenant, other than her badge, and is obsessively in love with her already, wanting to make her his 'Queen' right from the very start of the drama. The Lieutenant bares this oddity of affection and due to the solid acting skills of Kim Go Eun, makes you think she loves him back. I must say, Lee Min Ho truly drags this drama down with his lack of acting ability and the story being too focused on him. All of his lines sound the same and are delivered in a manner that is cringe-y or as bland as if he was reading off a sheet of paper.

As you progress on in the "story", it becomes a jarring game of hot potato between dealing with the main villain [Uncle Baddie] of the story and the romance with the shots happening either too quickly or too slowly and then BAAMM suddenly, we get romantic moments between our leads confessing their love ever-so desperately. This is a heavy handed attempt to make things thrilling without offering any development or consequences. The side characters with enveloping stories that interact with defeating our big uncle baddie are constantly placed on the back burner or simply not given the proper time to develop. The ideas for product placement has more intended use throughout the drama then the actual plot lines which only deepens the disappointment of this drama.

The timeline in this drama is a complex layer of complete garbage that neither makes sense nor can be resolved to any full effect. The drama was clearly not properly thought out and it shows with how chaotic episode 12-16 episodes are. It serves up unwarranted fan service over quality story and characters. The characters themselves are either too flat to be brought to life or stand on their own due to the poor quality of the script.

Woo Do Hwan's Jo Eun Sub / Jo Young, Kim Kyung Nam'sGang Shin, and Jung Eun Chae's Jae Goo Seo Ryung / Goo Eun Ah characters are scene stealers and make the drama more bearable but aren't necessary outstanding in their own right just by lack of competition. Woo Do Hwan has straight up WON the heart of so many MDL'ers and has been meme'd endlessly, which can be the only true accomplishment this show has achieved.

Finally, the saving grace of this drama is that it is dressed well in terms of cinematography and costume design. With a budget so high, it is hard NOT to be dressed well. It's money, however, could've been spent better. This is truly the type of drama that once you finish it, if it disappeared from your life the very next day, you wouldn't be losing out on anything.
