THE FUSE

Once ubiquitous in American theaters (and still quite healthy in Taylor Sheridan’s domain), big-screen Westerns are relatively scarce these days. When such tales do surface, however, they’re increasingly comingled with a genre that’s very much on the rise: horror. The latest such shotgun marriage, “Killing Faith,” is a somewhat murky and unsatisfying one. Still, its intriguing premise, able cast and bursts of violence hold attention even as writer-director Ned Crowley’s execution never quite realizes his concept’s potential. After a limited theatrical stint last month, Shout! Studios’ release is now available on demand.
