“Red Letters” (*1/2 out of four) was an earthbound supernatural thriller about two private investigators (Jim Klock and Mike Capozzi) who are assigned on a case involving paranormal activity which leads them straight into the heart of darkness and the hands of satanic evil which proves to be more than meets the eye. Ominous opening titles and beginning are a false alarm, as film soon dovetails into a swamp of spiritual hokum and bad acting. Klock also co-wrote and directed this clunker
