Interesting plot, great casts & everything but ruining my screening experience because of the sound company this show were using. Especially the sound effect during fighting scenes. What's up with using "spy music" for most of the fighting scenes instead of the sound of fists, kicks & slams? It decreases the "gripping & adrenaline" feel of the show. It's also making the already fake action scenes . :( In other news, Lee Soo Hyuk's voice is super sexy.
