Stuart Galbraith IV of DVD Talk had a small role in the film, writing "The project began around 1983–84, and was still shooting as late as 1998 or '99, when this reviewer was enthusiastically recruited for a bit part." In reviewing the completed project in 2006, he shared instances where science fiction and horror films of the 50s and 60s had been the target for satire and parody by "neophyte directors", and wrote "Rarely are these misbegotten projects made by filmmakers who actually like or understand the nature of the films they're sending up, and rarer still are they actually funny, striking that delicate balance between an affection for the genre with a recognition of its sometimes silly cliches and successfully translating this into humor." He noted that "The Naked Monster" was successful in striking that balance, but that it was "overlong and will appeal mainly to an audience weaned on the myriad films it references", and that the film's humor "wisely varies" from sight gags and bizarre non sequiturs to plays on words, in-jokes, and unashamed bawdiness, with its dialogue "played with straight faces", and the film dialogue being "often funny precisely because it's only very slightly askew". He concluded by writing that the film "would probably play a lot better cut even tighter, say trimmed of another 15 minutes or so," as "The style of humor tends to tax the viewer after an hour, and the climax drags on much longer than it should."
