The Bioscope (April 1932) outlined the plot as: "The story tells of a young man's adventures in a large country mansion with a scientist who is engaged in forwarding his theory that rejuvenation by the transfer of certain glands is more than a possibility. A girl is, of course, involved to supply the necessary love interest, and a misshapen creature, victim of the scientist, supplies the thrills".
The Bioscope wrote: "This adaptation of a story with a Frankenstein theme is so theatrically staged, poorly mounted and lighted and acted with such amateurism that it never for a moment convinces. ... Widgey R. Newman, who directed, has had recourse to all the stock gags to obtain his eerie atmosphere, amongst which are a constantly howling wind which, by the way, is more fierce in its intensity inside the house than outside, and a generous sprinkling of skulls and skeletons. Haddon Mason, who plays the part of the young man, displays an unusual lack of animation, Eric Adeney, as the professor, overacts considerably, while Isa Kilpatrick gains some little sympathy in the heroine role. The Cockney expressions from Wally Patch are a bright spot ecording is indifferent, with the voices often appearing entirely detached from the speakers."
Kine Weekly wrote: "A lurid professor and an ape-like monster, the result of the former's experiments in brain grafting, figure in a thriller calculated to raise the hair of not too discriminating patrons. Although the acting is fair, production is weak,and the story not sufticiently convincing to stand on its own merits. ... Eric Adeney delivers his professional jargon with effect, and is quite an asset in working up the thrill. Haddon Mason speaks well as Kemp, though his performance is a trifle wocden. Wally Patch sustains the light relief as an ex-criminal butler. Action is decidedly jerky, and except for its opening sequerices at no time convincing. And yet there is a short-lived thrill to be obtained from the character of the ape-like man whose features are cleverly made up. A sinister feeling likewise pervades the character of the professor. Dialogue is generally artificial."
The Daily Film Renter wrote: "Weird story of a fanatical scientist, with heavy dramatic atmosphere throughout. ... The story is somewhat meagre, and incredulous as mystery stories are generally, but Haddon Mason as Ronald Kemp acts adequately, and Eric Adeney as Professor Bandov is calculated to supply the thrills. Light relief is supplied by Wally Patch as Jorkins, the butler. A mystery atmosphere pervades throughout, and patrons to whom this fare appeals should be amply satisfied."
