In my memory, this movie was marketed very much as a comedy that happened to include an element of spying. Or at least that was my impression. The first part of the movie was relatively charming, as we were introduced to the main flower boy trio, and the mundanity and charming qualities of rural village life. But the movie took a very strange and unexpected turn into rather dark territory, some of which touched on themes like loyalty, and I just didn't understand why the characters took the actions they did. There were a number of themes that were so underdeveloped that could have made the movie more whole - the spies' relationships with the villagers, Sohn Hyun Joo's commander character, who I was expecting to have more significant screen time, but again, a waste. You can call me a bitterly disappointed viewer.
