From retrospective reviews, Gary Westfahl in his book The Spacesuit Film: A History, 1918-1969 noted that the film contained "shoddy special effects" and recalled "Saturday afternoon serials more than science fiction films of the 1960s". Westfahl referred to the film as "one of the era's most reviled genre films."
