Your indie horror movie loses its underdog credibility when a random cat is used as a jump scare, twice. That’s an unwritten rule I hadn’t realized until “The Unspoken,” an anti-thrilling horror movie that scapegoats its narrower production means to rely on even slimmer narrative imagination. That the story is never scary is the least of its problems, as the production itself brings to question intent, aside from giving select audiences and VOD another title to chew on over Halloween weekend. But with that comparison, “Tyler Perry’s Boo! A Madea Halloween” made me more anxious than anything here.
