The Monthly Film Bulletin wrote: "Though Charles Eric Maine is credited with the script, the credit titles make no mention of his intriguing but surely unfilmable novel. The film, in any case, is a tepid adaptation which scarcely suggests the genuinely terrifying possibilities explored in the book. The "dream sequences" (as they are called) are a mistake; the "electronic music" (as it is called) loses much of its effect through over-use. All the same, the theme gives this science fiction melodrama a certain originality."
Variety wrote: "
The Electronic Monster offers one or two novel twists to an old cinema standby, the one about the diabolical scientist-sorcerer who creates disciples by toying with human brains. Since modern audiences seem intrigued with dramati-clinical sorties into the mysteries of the human thought mechanism, the Columbia release generates a certain pseudo-scientific appeal that should qualify it for comfortable second-billing. Outside of this quality and the fact that it has been produced wiih cinematic skill, it's a strictly routine melodrama. ... The dream sequences give the picture a curious dash of sex." Chibnall and McFarlane in ''The British 'B' Film'' wrote that the film: "generates a genuine strangeness of atmosphere through its use of electronic music and special effects." In
British Sound Films: The Studio Years 1928–1959 David Quinlan rated the film as "mediocre", writing: "Main sufferers are the audience who have to sit through this unconvincing tosh."
TV Guide noted, "an intriguing feature in that it was among the first to examine the possibilities of
psychological manipulation and
brainwashing." ==References==
