It's all too easy to dismiss science fiction and fantasy stories as escapist nonsense. But there's ultimately something despairing about the charge of running away most readers of these genres encounter at some point. It tends to come from an authority figure of some kind -- a teacher, a boss, a parent. It is often well intended. But even as they make the accusation, you can hear a part of them whispering quietly, "I want to escape! I want to imagine! I want to dream!" Unfortunately they've forgotten how, and reality is too important to escape from -- even for a moment.
