Not sure how come the high point and hype about this Drama,media keep boast this the best drama ever made in Korea. All cast are my favorite but whole tempo of the story is too draggy and boring. Cgi is best at Asia but still get knock out by Marvel studios. What keep me watch till to 10 episode is the pretty look of the actress only. A copy version of Bad Boys and X-Men but they are far more better than Moving in storyline and character Development. There is no main character and character so plain and dull that I can't bother what happen to them. Everytime that's a tension moment but stop half way or u already know what's going to happen next. Try to make a Dark DC version by using dark shoot but the whole camera screening is no creative and traditional. Still a watchable Drama if u have too much free time.
