The movie is 《封门诡影》 and it starts of with the fear of abandoned villages as if the reason was for villages being emptied out was supernaturally evil. Fengmen (literally closed door) Village was inexplicably abandoned. I’ve never never seen Blair Witch, but this movie seems kind of like, but with ghosts and dodgy fengshui. Our intrepid hero teaches psychology and has issues because unable to understand evil within his cognitive framework. It’s all in your mind. But not really. Cut to evil cackle.
