Texas Chainsaw Massacre?
The bizarre cinematography of this movie in itself creeped me out, made the whole event seem surreal, not sure anything was actually "real" so far as the (so called) story was concerned.
There was also the unknown state of 'grandpa,' was he alive? Or dead? You never did know...
Do those 2 factors make Texas Chainsaw Massacre "sci-fi" on top of the obvious horror? If so, it would be on my top 20 list. It's just so different in overall appearance from anything else I've ever seen.
A friend of mine forced me to watch it a decade or so ago, and I'm glad he did. Unusual experience. (ps- this guy is a first officer for American Airlines... the operator of the environmental ships in Silent Running. We started our aviation careers together, I went corporate, he went airline... I told him he'd end up flying for the US equivalent of Aeroflot. We're almost there!)
