Ambiguity works in film noir, mystery stories, and thrillers that depend on paranoia to add to the suspense. Ambiguity in a horror movie, at least in this one, remains just that -- ambiguous. Soul Survivors is a generic teens-in-trouble saga that strings together gothically dressed scenes featuring creepy characters reciting circuitous dialogue that eventually leads to nowhere. And not anytime soon. The 85-minute running time seems like forever, and the film makes the gravest mistake a movie can make -- it's boring. The characters are unengaging or repulsive, the would-be surprise ending is anti-climactic (you can see it coming from Luke Wilson's first appearance as a concerned priest), and the plot spins its wheels at such a leisurely pace, you find yourself shouting at the screen to just get on with it. Stories about supernatural limbo are by nature ambiguous -- the character is, after all, between life and death, what could be more uncertain? -- but unless the director has the deft touch of The Sixth Sense's M. Night Shyamalan, the proceedings can prove pointless. Soul Survivors proves that point.
