Remember, science fiction literature is not a necessity. I'm gonna take my science fiction money and buy a beer. Now, that depressing view wasn't all-pervasive in science fiction. It was a ratings failure, but not a death knell for optimism. That resurgence, however, sometimes appears to be solely in the novelization arena.
People read science fiction for the entertainment .
Oh, sure, we're all interested in seeing what might be around the next corner, and science fiction seems to have a knack for guessing right, but at the most basic level, we want to be entertained. And somtimes, it works. Optimistic tales, on the other hand, by their entertaining nature, attract readers. And though they may not spur the reader to take action, they can often depict worlds that the readers want to experience, and, desiring it, will create for themselves. When I was young, I watched Star Trek on television, and knew I wanted to explore the galaxy on that wonderful ship.
