If it's low budget, scary or a bit brutal then it's psychotronic. The term was dreamt up by Michael Weldon after he reviewed hundreds of quirky and obscure films including the 1980 Chicago cult sci-fi title The Pscychotronic Man. The sometimes brilliantly expressive hand-rendered titles are probaby the highlights. They run from 'The Adventures of Buckaroo Banzai' to 'Zontar: the Thing from Venus' and include spaghetti westerns, horror and exploitation films, made for a quick profit with little thought for merit.
