P. J. Snyder reviewed Saturn 3 in Ares, and commented that: “Saturn 3 is a sloppy, shoddy production, of the sort that someone out there thinks SF fans just eat up. One hopes the producers and directors working the genre will realize this audience demands more than a leggy blond being chased by a robot. They may have such limited visions, but the audience doesn’t.”[25]

On Rotten Tomatoes, the film holds a 31% approval rating based on 16 reviews.[26] On Metacritic, the film holds a 9/100 based on reviews from eight critics, indicated as “overwhelming dislike”.[27] Film critic Roger Ebert gave the film one star in his review, criticising its screenplay for having a “shockingly low” level of intelligence, citing moments disregarding the laws of physics, the love triangle between Douglas, Fawcett and Keitel, as well as other details.[28]
