Like the other reviewer I think this is 'made for me' - three strong female leads including my current favourite screen actor Choi Kang Hee - and the production is excellent and it is written very well, and all the interactions between the characters are fine (particularly like Kim Ji Young's 'Mi Soon') but it just doesn;t hold together - and almost immediately I realised what was wrong - all those idiotically extended fight/action sequences, they just go on and on to no purpose whatsoever, taking up a significant percentage of most episodes. The series would have been 10 eps top without them, I am sure. I feel cheated - so many good aspects to this and yet I didn't enjoy it, and would find it hard to recommend. If this had concentrated more on the three main characters, obviously some some action and character peril for tension, it would have been brilliant.
