From contemporary reviews, Weaver described
Invisible Ghosts as getting the "reviews it deserved." The
Motion Picture Exhibitor described the film as "complicated and unbelievable" while the
New York Post gave the film a "Fair" rating, noting a complex plot and the "buildup of suspense in a horror/drama, is imperfect." The
New York Daily News gave the film a one star rating, declaring the film to be a "ghastly bore" finding that Lugosi was "not at his best" and the direction of
Joseph H. Lewis was "inadequate". The
Los Angeles Times said the film was "head and shoulders above the average horror picture. Its superiority is based on the fact that spine-tickling qualities stem from a psychopathic and psychological situation rather than a purely physical one, imparting a Poe-ish flavour... Lugosi is, of course, superb in his work, being master of all the horror tricks but never overdoing them". From retrospective reviews,
Leonard Maltin's Film Guide awarded two out of a possible four stars, calling it "Better written and directed than most of Bela's 1940s cheapies, but still a far-cry from
Dracula". ==See also==
