There is something very Korean about this film. It again represents the fascinating combinatoin of the Korean film industry's adoption of Hollywood production values and syntax to a quintisentially Korean theme: the essential brotherhood shared between those in the north of the Korean peninsula and those in the south, especially among those in the opposing militaries.
What do we learn here? That the avergae guy on both sides of the DMZ is genuinely good, decent, caring and has far more in common than at odds with his brother/comrade on the other side. But more than that, we see that the source of conflict are the higher-ups, the institutionalization of the conflict, and the international presence that seems at best interested in helping each side gloss over any subtleties in the situation and, at worst, ready to add fuel to fire (or, at least, the US is accused of such by the Northern soldiers).
Quality, heart, enough intelligence, not too sentimental. Recommended.
