[DVD] "Lesbian Vampire Killers"

This movie came out on DVD last week - "Lesbian Vampire Killers" - and I have no interest in it at all. That is, except for the following conundrum that keeps plaguing me ever since I knew of this film's existence (for which I can thank Fangoria Magazine):

Is this a movie about lesbians who kill vampires, or vampire killers who target lesbian vampires? If the vampire killers target lesbian vampires, do they leave "regular" vampires alone, i.e. heterosexual female or male vampires?
