"If Alfred Hitchcock’s 1960 Psycho is considered the grandfather of the slasher flick, then Mario Bava’s 1971 giallo A Bay of Blood can be designated as its demented uncle."
—Film Frenzy
"A brutal, bludgeoning film, utterly misanthropic in its outlook, and all the better for its refusal to compromise in exposing human nature at its ugly, imitable worst."
—Little White Lies
