Horror High/Twisted Brain has a Z movie reputation but is a likable exploitation film. It is entirely predictable. You can see how everything is going to happen the first twenty minutes set up the parade of bullies and sadistic teachers and the remainder of the film consists of them being dispatched. Despite its obviousness, there is a certain amusement to the gore scenes a teachers fingers being cut off in a gullotine, a janitor being shoved into a vat of acid and his skull later floating to the surface, and a gory sequence where the coach is stomped to death with a set of spiked running shoes. Despite its cheapness, Horror High/Twisted Brain is a surprisingly pure-hearted film. There are no gratuitous sex scenes, for example, and the emotions are adequately conveyed. The only thuddingly obvious moment of Z filmmaking that turns up is when someone wanders into shot with a clapper board.
There are some good performances, with Pat Cardi making a convincing nerd and Joy Hash strikingly mean as Miss Grindstaff. The only recognisable name in the cast list, Austin Stoker, is cast as an amusingly obvious attempt to emulate the then fad for hip Black detectives (the Blaxploitation film) created by Shaft (1971).
The horror spoof Return to Horror High (1987) is often thought to be a sequel but is unrelated.
