After watching this series, i came to realisation that some people turn their brains and heads upside down when watching dramas, I don't think a normal person in his or her right senses would watch this and still have negative reviews. This is one of the best korean action series I've come across, the story, writing, casting, and acting was just to superb. So i don't know why someone, all in the name of senselessness criticize this drama.................I'm so pained ooo.............................
