I am mining facebook again, since I make a lot of comments there. This is in response to post-apocalypse stories that seem overly cozy. The one being discussed (one I don't know) was described as so beautifully crafted that it made the ruined world seem tidy.
I read SF as a kid, because it was about the real world, which included nuclear holocaust and McCarthyite witch hunts. I guess one of the appeals of good SF is horror and despair, and the roughness of SF, the lack of polished style, may have contributed to a sense of reality. Would you polish your sentences, if you were dying of radiation sickness? --I don't like genre horror, maybe because the horrors in horror are not usually real ones. But since I don't like genre horror, I haven't read enough to be sure why I dislike it.
