M. J. Simpson noted that the final film took 21 years to create, and acts as "both an homage to, and a spoof of, 1950s sci-fi and horror movies". The reviewer's initial impression was that the film was "cobbled together using two VHS machines, a stopwatch and the complete literary works of Bill Warren", and that the story was not what mattered in that the script "is basically what you would get if you threw every monster movie plot filmed between 1955 and 1965 into a blender, then scooped out 90 minutes’ worth and baked at gas mark seven." The reviewer praised the film's manner of not taking itself too seriously as such was the "central conceit of Newsom's hugely entertaining film". The reviewer then listed the number of 50s and 60s genre icons that returned to reprise their characters from other films, and noted it as Kenneth Tobey's last film, and that actors John Agar, Les Tremayne, Robert Cornthwaite, George Fenneman, Robert Shayne and Gloria Talbott died before the film was completed and that Paul Marco died within a year of the film's release, and remarked that the film "stands as a warm tribute to each and every one of them".
