I started watching this drama because of the cast mainly and i got to tell you it didn't disappoint me at all. So let me start with the story, well the plot in this drama is one of kind because instead of adding action elements to the political part this drama has added a scientific element and i have to be careful when i say scientific element because in big part of the drama it's the main thing. while the scientific part was brilliant and you can see how much effort the directors and the producers put in it the political part was kind of flat, even boring sometimes but honestly this didn't bother me that much, i still enjoyed the story and the plot plus the comedy moments in the drama were really funny ^_^. How about the casting, well as i said before i watched the drama because of the cast and honestly all the actors were great starting with song il gook, kim sang kyung, lee ji hoon and my personal favorite kim do hyun who did a great job as lee chun and made me really like this character a lot. Going to the music i have to say it was really nothing special, there's no Osts in this drama so don't expect much anyways there were some tracks which i really liked when they were played and overall the musical arrangement was good. In the end i want to say that i really liked this drama, it wasn't perfect or epic but it was really fun and amusing to watch.
