The Invisible Maniac (1990)

"A budding young scientist lad is caught by his mom checking out the lady across the way with his telescope, whereupon she lectures him on the evils of women. Twenty years later and all grown up, the scientist announces his theories of invisibility, and his colleagues laugh, to which he responds by killing four of them. He escapes from the loony bin and gets a job teaching summer school physics at a high school. The students decide to tease him about the same time as he perfects his invisible juice, and he goes on a spree of vengeance." (from the IMDb)

You know there are some films which you wish you'd never bothered to watch in the first place. This is one of them.

The story, if you can call it that, is that an insane high school science teacher perfects a serum which makes him invisible so that he can spy on pretty girls taking more showers than necessary. Ok, so maybe taking revenge on the students that enjoyed making his life Hell has something to do with it later too, but as far as I could tell, the plot only exists as a contrivance to link all the nudie bits together.

The nudie bits are nothing special either. Even though "The Invisible Maniac" was made in 1990, it has a complete lack of eroticism compared to even much earlier sexploitation movies and is just laughable (but not in a good way!). You get to see quite a few nice boobies and bottoms, but that's all. There's absolutely no threat of rape at any point, so it's nothing but puerile voyeurism.

Noel Peters as Kevin Dornwinkle.

With pitiful effects, lacklustre kills, only one gory aftermath worth mentioning, and nothing scary in it whatsoever, "The Invisible Maniac" is easily one of the least horrific "horror" movies ever made. The acting is terrible, and if this is supposed to be some kind of comedy, well, it's considerably more irritating than funny.

There are probably certain people who find this type of low-budget crap entertaining. They are probably also the sort of people that think the late former pornstar Savannah was a brilliant actress and that her role as Vicky in this drivel is her best work.
