Mind-blowing plot, superb acting, stunning visuals, heart-tugging soundtrack - this drama has it all and more. Lee Min Ho's depiction of a handsome, elegant, benevolent and scientific king is perfect, as is Kim Go Eun as a dedicated, no-nonsense, taekwondo-master detective who decided to be brave because not everyone can be. I love how their relationship and chemistry developed from her initially thinking he was a crazy deluded weirdo to that heart-stopping moment when she found out he was not. The drama gets better the more it is watched. It is filled with delightful nuggets, the humor of which I missed on my first viewing, such as when she told him to "park your horse on the side road to the right" or when she carelessly tossed away his watch after he told her to take good care of it or when she sneakily took his DNA sample while he was explaining the parallel universe theory or when she told him his eyes look like those of a criminal and he stopped his explanation about quantum mechanics to say, "I don't know about other things, but I know my eyes are charming. I was born with deep-set eyes." Ha ha ha, an honest king, too!
