She brought up a really valid point: Authors of fantasy and fiction are forced to illustrate their ideas with a strong connection to reality, and non-fiction authors have to present "unbelievable" and explicit stories to have success. What do I mean by that?
How many times have you watched a science fiction movie, and someone said, "There's no WAY that could ever happen. So unrealistic"?
Or perhaps you've noticed that folklore and fairytales have been kicked to the kids' curb. We want tangible stories. We want them to be believable and real. Because we're losing the ability to imagine and sustain creativity. It has to be presented to us in a way that our minds will readily accept it; no work involved.
Then you have the based-on-a-true-story stories. We want to hear the nitty gritty stuff that makes us cringe and share it with our friends. There's something innate within us--that I don't want to try and dive into right now--that craves that kind of alternate reality within reality. Life, for the most part, is pretty ordinary. I don't know about you, but I wake up, eat breakfast, go to work from 5:00 a.m. until class starts at 10:00, study some, eat some more, climb a little, socialize, and sleep some more.
So indulging in the extraordinary parts of someone else's life gives me a weird thrill. Does it do the same for you? I would think so.
