After celebrating (and subverting) ’80s horror with “The House of the Devil” and classic bump-in-the-dark ghost stories with “The Innkeepers,” director Ti West has broken away decisively with his new film “The Sacrament.” (West brought the film to the Wisconsin Film Festival in April, and it’s out on DVD this week). The question is whether in shifting away from smart homage and into something more distinctive, West has lost more than he’s gained.
