From retrospective reviews, the authors of the book "Universal Horrors" declared the film to be "the least ambitious but hardly the least entertaining of Universal's widely varying series" noting it's "no frills approach to its subject matter" declaring it better than "The Invisible Woman" and "Invisible Agent" but not as strong as "The Invisible Man" or "The Invisible Man Returns". Special effects in the film were described as "have a slapdash quality" with only a few pulling of "startlingly effective tricks."
