Ultra-Violence (or UV) forms part of the film classification spectrum, which is a method used by experts to classify films in a spectrum and may be considered analogous to the electromagnetic spectrum - except it is real scientific fact and not merely Communist propaganda. Ultra-violence films tend to come in two types, known as Near Ultra-Violence and Extreme Ultraviolence - the former of these is widely thought of as pathetic and for losers who can't stand the sight of blood, and among film makers is considered a failure.
