Very similar in look and feel to "The Conjuring" (2013) and "Insidious" (2010) but with central characters that are teenagers rather than adults. The similarities make it feel a bit formulaic, but it's a good formula. Scary and frightening like a haunted house movie (the movie's self-aware opening narration describes itself as a ghost story) ought to be, its intensity is too much for PG-13 but lacks the explicit violence and gore typical for R. Three jump moments were quite effective, which again indicates a PG-13 level of scariness, but the overall creepiness of the unfolding mystery is even more compelling. Rather than coming apart in the third act, the movie features a complete ending that wraps up and justifies the story. Kudos to the prop maker who created the vacuum tube-era radio box, one of the creepiest "characters" in the story. This movie is well-made, scary, and a welcome addition to the modern horror genre.
