I finished In The Days of the Comet last night. The earth passes through the tail of comet and a green gas puts all living things to sleep. When they awake, what happens? Is the world overrun with zombies? Do all the animals start talking and hunting down humans? Does humanity gain awesome psychic powers?
I don’t know what happens to the rest of the animal population but humanity wakes up and … is Enlightened. Everybody gets together and starts building a socialist utopia. The hero rejects his lover and then, as he becomes more enlightened, his limited picture of love expands enough to include her as she is. Happy ending.
