Arthur D. Murphy of "Variety" wrote, "'Futureworld' shapes up a strong sequel to MGM's 'Westworld' of three years ago ... Richard T. Heffron, on his second feature directing work, keeps the personal drama moving smartly through the gadgetry montages." Kevin Thomas of the "Los Angeles Times" called the film "an extreme rarity, a sequel that's a decided improvement over the original." Gary Arnold of "The Washington Post" wrote, "Unlike 'Westworld' there's nothing shrewd or compelling behind the events in 'Futureworld,' where the big mystery is just an old wheeze—the managers of the park are power-hungry scientists who clone influential guests and order the clones to dispose of the originals." John Pym of "The Monthly Film Bulletin" expressed disappointment that the scriptwriters neglected to explore the interesting implications of self-programming robots and instead "seem content to do little more than lead the players through the standard diversions of a caper movie."
