There’s a line late into “Eu logy for a Vampire” uttered by the tormented Father Anthony — and he seems to be speaking for the filmgoer who unwittingly bought a ticket. Asking God for forgiveness, he cries, “I’ve suffered enough!”

In brief, so as not to extend the suffering, “Eulogy” is set in a rundown monastery in an indeterminate time and isolated location. There, a handful of brothers experience male bonding — literally and sometimes graphically — while some become blood brothers of the vampire type.

In a prologue, we see Anthony (Wilson Hand, looking like Anthony Perkins) kill a brother who refused his amorous attentions.

Twenty-five years later, when a stranger with no memory is found on the monastery grounds, Anthony has flashbacks of his victim.

Unlike the modern glamour-vamps of “True Blood” and “Twilight,” this group of smitten and bitten men are no fun at all. That is, unless you like heavy breathing, underwear sniffing, cringe-inducing blood sucking, murder by stabbing or hanging, plus grainy, underexposed cinematography and stilted acting.

Running time: 103 minutes. Not rated (sodomy, graphic knife play, blood, gore). At the Quad, 13th Street between Fifth and Sixth avenues.
