This movie had an odd effect on me. It worked like a punch in the stomach: it hurt a lot and for a moment there I was stunned and couldn't think of anything else, it was pure feeling. After a while, however, I began putting the whole experience under a more rational light and I was left a little puzzled. Like someone else here pointed out, I too fail to see a logic in the actions of all involved. The title of the movie, which is not randomly chosen but should explain the whole film, promises something that wasn't fulfilled. If the intention of the writer was to create a story of secrecy and greatness, it excelled at the first and failed at the second, since there isn't anything heroic, or shiny in the order they are given and the way they handle it. This dichotomy would work if the whole film had been built on the futility of nationalism, if it were a big, sarcastic accusation, but it isn't. It talks about three young guys and the way they deal with facing a different reality from the only one they have known and learnt as kids. I wish we had had the chance to see that bond with the 3 spies and the village building up, but we don't. We are left to imagine whys that never get a because. My reason for the high overall mark is the acting, which in my opinion fully deserves a 10. Kim Soo Hyun in particular does a fantastic job in portraying this double version of himself. And here's the rub: the movie works only on a visual and pure feel level. Once the plot has been dissected and your mind fills with question marks, what lingers is the beauty of all three guys, particularly enhanced by ultra smexy combat scenes, murderous looks and a few very effective friendship scenes. My desperate attempt at reasoning miserably failed when confronted with the three of them on screen, just like any other adolescent viewer - problem is, I'm no adolescent anymore. I feel there wasn't enough music in the movie to speak about it in detail. It was there, but I forgot. I'm still debating about ever re-watching this movie. I won't be thrown a second punch, that's for sure, so I wonder whether it would be of any use to re-watch something that was pure feeling in the first place, once the feeling is gone.
