Night Visitor

A pair of satanists drive around in an old black Cadillac, picking up hookers to sacrifice. A high school student who's always telling tall tales (I was late to school because my mother burned her hair when her hairdryer exploded!) tries to get closer to a female friend, and meets a sexy older woman who moves in next door.

The high schooler witnesses a murder, and even though when the police show up the body is there as described, murdered when and how he described, they don't believe him when he says who the killer is. I found that a bit hard to believe, even given his penchant for making up stories.

A bit randomly, his best friend is a smartass named Sam Loomis, like Donald Pleasance's character in Halloween.

The satanists (of which there are only two) kill some women in their car, and some in their house. They don't seem to actually have any satanic powers.

There's a few recognizable faces in the movie. Michael J. Pollard plays a sort of character he's played before, a man with the mind of a child. Henry Gibson shows up briefly as a police consultant on satanic crimes. Richard Roundtree plays a cop, as he has a thousand times. Elliot Gould is a family friend who the student tries to enlist.

The movie never really takes off at any point. The ending concludes things, and then follows with a musical montage and a freeze-frame which struck me as silly.
