Moria says, "Runaway manages a competent bevy of ideas but does seem a little pat at times." DVD Talk calls it "blunder of a Sci-Fi epic masquerading as decent cinema" and concludes, "This is really an awful film from start to finish. Not one moment of redemptive viewing. Save yourself from the horror! Oh the pain, the pain. (Thank you Dr. Smith)." Mutant Reviewers concludes, "It’s not that there’s no value here, it’s just that Runaway was already dated in 1984, and no amount of lip fuzz can overcome that fact." Rotten Tomatoes has a critics score of 47% and an audience score of 33%.
