The war (or specific battles/events during the war) between North and South Korea has been the backbone of quite a few South Korean movies. Most of them really get something good out of this mess. And this movie is no different. Staying mostly on one side, you still get to see "the enemy" and their points of view from time to time. It is superbly cut together and acted very fine.
While I'm not sure about how accurate the movie is by presenting the events (I'm guessing it takes a few creative freedoms), it does not hold back when it comes to punches (or bullets for that matter). The lines between good and evil are really thin. You might argue there are none. The grey area is very big, that is one thing that is very true though. Not the best war movie to come out of Korea, it still is superior to a lot of other war movies.
