Very impressed with depiction of military uniform. So much so, I looked up South Korean military and discovered all males do 2 yrs of service. The salutes, wearing of the beret, correct blousing of boots. The perfect actors to play military roles. The sense of duty and honor captured. The difficulty of deployment from loved ones. The challenges of a soldier building and maintaining a relationship with a civilian. All depicted very well. Throw in romance, danger, killer fight scenes. Excellent emotional range of actors. Very good story line and a unique ending.
