We went to see this movie last week. It was pretty good. More interesting to me is the fifteen-minute documentary on YouTube about the man who inspired the movie. It's not unhealthy to be reminded now and again on the demonic forces all around us. I think we might all take life more seriously if we were more aware.
There is some language; be ye warned.
Oh, Ralph Sarchie has also written a book, "Beware the Night," which I intend to read just as soon as it drops on our doorstep.
