South Korean director Su-chang Kong's 2008 military horror outing "The Guard Post" (aka "G.P. 506") opens with a scorcher: A squadron of heavily-armed soldiers storm the seemingly abandoned G.P. 506, an outpost which lies along the tumultuous North Korean border. Once inside, they discover the horribly mutilated bodies of countless young troops, all of which are scattered haphazardly around the base. The culprit, wide eyed and wild, stands before them drenched in blood, a large axe clutched in his hands. It’s one hell of a way to start the picture.
