So things really aren't going well, not one bit. The apocalypse has more or less happened. Most cities are destroyed. And there's a virus going around, and three-quarters of the people on Earth are infected. Oh, yes, and about that virus? It turns people into zombies - not literally, in a textbook definition sense, but zombielike, with a lust for flesh, poor dental hygiene, a tendency to attack in packs, to walk funny, have jerky movements and to show a certain exuberance in destruction. Anyway, this is the world of "Maze Runner: The Death Cure," the third installment in the "Maze Runner" trilogy, a kind of destitute man's impoverished cousin's answer to the "Divergent" series.
