nitratediva’s review published on Letterboxd:
One of the best variations on the "can we communicate with the dead?" theme. Karloff's grief-induced derangement is moving, but the shudders largely come from Anne Revere, whose domineering, sociopathic medium is a B-movie Lady Macbeth. Austerely Gothic art direction, the Iron Maiden-like metal hoods, and an evocative voice-over by the scientist's daughter contribute to a memorable, if uneven 65-ish minutes of entertainment.
