I wrote the plot description for this on IMDb a million years ago. I tried to demonstrate how horrible this movie was with my tongue firmly implanted in my cheek, while giving an accurate description, and not making it a review. Some comments compared ZPG to Logan's Run???? Logan's Run is brilliant and a frightening "what if" scenario for the human race. How about comparing it to 2001: A Space Oddyssy or even Citizen Kane while you are at it? And Soylent Green, though not brilliant, SG is a far better movie than this one, and a more plausible future. This movie should have been featured on Mystery Science Theater 3000--only on that show would it have been worth watching. Avoid this film like the plague!
