A mixture of H.P. Lovecraft’s From Beyond, The Blair Witch Project, and the real-life Project MKUltra experiments conducted by the U.S. Government from the 1950s to early 1970s, Banshee Chapter is an impressively adept and character-focused horror movie.
I seem to recall being entertained enough by it to justify watching it. I may have preferred it if it hadn’t been found footage style which was all the rage back then.
