Outpost

In a European country devastated by the war, a group of six mercenaries leaded by DC (Ray Stevenson) is hired by the engineer Hunt (Julian Wadham) to protect him in a travel to a no man's land. In accordance with Hunt, he is the representative of a group of investors and he has been assigned to visit one facility in one of their real estates. When they arrive in the spot, they find an old Nazi bunker with a pilot machine and evidences of gruesome experiments with human beings and one survivor. While protecting the outpost, they are attacked by invisible enemies; when Hunt discloses the truth about the mysterious device, DC realizes that they have to fight to survive to an invincible supernatural army.

"Outpost" is a horror movie that keeps a claustrophobic atmosphere, but has many unexplained situations. Why the fiends did not kill the whole group at once? Why the fiends became corporal? Why the leader of the fiends stays in the bunker? Why the mercenaries keep shooting the fiends if they know that their bullets and mines are ineffective? In the end, "Outpost" entertains, but I really prefer the South Korean "R-Point" or the British "The Keep" (1983) that give better explanation to the supernatural events. My vote is six.
