Contemporary horror films , often ruthless in their eagerness to deliver the ostensible scary goods, frequently decline to adhere to their own internal logic. “The Gallows Act II,” a thoroughly undistinguished follow-up to the 2015 film “The Gallows,” seems, for much of its running time, not to have any internal logic to begin with.

After a found-footage-style prelude establishing the telekinetic, or whatever it is, power of the play-that-kills called “The Gallows,” the movie, written and directed, as the first one was, by Chris Lofing and Travis Cluff , brings us into a fresh world of high-school drama. The eager aspiring actress Auna (Ema Horvath, who has a touch of young Hilary Swank) moves in with her older sister to attend a new high school with a stellar drama department.
