Boris Karloff is deliciously spooky as the narrator who unfolds a trio of stories in Mario Bava’s immortal “Black Sabbath*.” Each tale involves people whose demons come back to haunt them in one way or another. Mario Bava is excellent in depicting various shades of terror, devoting bold and stark palettes of colors to each segment that add to the EC Comics vibe that Bava inadvertently conveys. “The Drop of Water” is the best and arguably most iconic of segment in horror movie anthologies, involving the classic comeuppance of a grave robber. In the early 1900’s, nurse Chester is called to a large house once owned by an elderly woman who was also a medium. After the elderly woman dies while seemingly in a trance, Nurse Chester arrives to discover the gruesome visage of the woman and helps to dress up her corpse alongside her incredibly terrified house maid.
