“Bunker” (*1/2 out of four) was an anemic horror thriller about a group of WWI soldiers (Roger Clark, Luke Baines, Sean Cullen, and others) trapped in an underground lair and soon find that a sinister force has overtaken them and is systematically turning them against one another and it’s a battle to the death to see who will survive. Plodding trifle in a claustrophobic setting but horror fans and WWI historians will find little of merit here; a few good special effects are film’s only value. “Junker” would have been a better title for this timewaster.
