If this enterprise were treated in a high-voltage way, this would be another low-rent horror film. West is more patient. He evokes the feeling of a long night in a boring job, during which Claire and Luke speculate about ghosts as a way of amusing themselves. Their relationship, based on humor and enigmatic affection, would be entertaining enough that if no ghosts ever turned up, we would understand. "The Innkeepers" astonishingly creates characters who are not only specter-prey.
