As a long time reader of both science fiction and fantasy, only about .1% is instructional or thought provoking, the rest is escapism or wish fulfillment, the modern version of the penny dreadful.
I am dissapointed by most scifi because I have such high expectations for it. So I have started to look to other genres that offer better quality on average.
Really? The usual image is that techie geek types lap up scifi and fantasy, which when done properly are all about the human condition.
