The plot of this was fantastic. It was riveting with good twists and turns without becoming ridiculous like so many fast-paced, thriller-type kdramas. Toward the end, I started thinking that the show was going on for 2-3 episodes too long, but I liked where they took the plot in the end. What keeps me from rating this 5/5 stars is the women in this show. Hang Ah was great when she was being a soldier, but as soon as she was dressed in civilian clothes, she became the most annoying, chipper, 1950s housewife. I found the princess character annoying too. Thankfully, the male characters made up for the women, and I loved the plot.
