A suspense, not horror movie
I would not classify this as a horror movie. It was not scary or gory to me at all. I think suspense might be a better description. It had one of the most creepy movie scores for it's time, and even now for that matter. The atmosphere, the creepy music, the killing scene at the beginning, and the amazingly vivid and colorful scenes make this a really good movie. I'm amazed this movie was made in 1977, and I'm glad I caught this on IFC a few years back, or I never would have heard of this movie.
