Vulgar is just that. A cheap, nasty but reasonbly watchable exploitation movie of the type that was being made in the late 70's. Sort of a less existential "Driller Killer". The film also has the sort of flatness and flabbiness that characterised much of this type of film.
The sorry tale of Flappy the clown and his treatment at the hands of a bunch of sickos isn't the greatest of stories and there are some agonisingly boring scenes but it is enthusiastically made with a caustic misanthropic eye.
The greatest controversy will doubtlessly be about the rape scene and its perpetrators. These three guys aren't gay - the father is shown as married with a kid and it is his two sons he commits his terrible crimes with. These are a family of psychopaths who delight in homophobic cruelty. "Lets make hate" Dad says as he begins his abuse of Flappy. For a viewer to automatically label the twisted protagonists gay is wrong. They are psychopathic rapists not gays.
The film raises some interesting questions but it just doesn't have the panache to answer them. Unlike "Happiness" and "Contre Seul Tout" there doesn't seem to be much thought behind the provocative nature of the film and certainly the filmmaking isn't as accomplished. A possible cult item of the future but far from an essential view
