Terrific Poster
I remember seeing this movie when I was 12 or 13 when it was released by the late, great Paragon Video Productions, who also introduced me to DOCTOR BUTCHER M.D., THE GATES OF HELL, BOARDINGHOUSE, JUST BEFORE DAWN and plenty of other horror/exploitation classics.
I haven't seen it since then, but I don't recall it being particularly good. However, it's got one of the best horror movie posters I've ever seen. Very creepy, very atmospheric, very intriguing... everything movies AREN'T these days.
