R-Point (2004)

A South Korean ghost story set in Vietnam during the war. A small platoon is sent to the R-Point location to search for a group of missing soldiers. The rescuers soon begin to feel as if something is amiss, a suspicion that's intensified by their own fears and the peculiar fog that covers the grassland.
The location is unusual for this type of story, the opposite of what we usually get, but Dir. Kong Soo-chang makes good use of it. It was his first feature; it's well-made, nicely shot, movement is precise, actors are good, editing is effective, etc, but the most memorable ingredient is the soundtrack, an eerie soundscape that does more than set the tone, it upstages everything else.
