That's a little harsh. If you drop the mutant superpowers aspect and just treat carbon plague as, well, a plague caused by nanites, you get a VERY decent and dystopian setting that works even as a re-vamp of CP2020. It's less "Escape from New York" and more "The Island". Less "Cyborg" and more "Gattaca".
Plus, I liked the key enemies (ISA Incorporated States of America und CDC Center of Desease Control FTW!)
