A great deal of science fiction — at least that which leaves a big mark on pop culture — gets potential readers and viewers in the door with a promise of escapism. Sometimes these tales feature a protagonist like Luke Skywalker who leaves his normal life behind and gets a chance to exchange the dreary and dull for danger and destiny, and we as the audience are invited for a short time to imagine ourselves getting whisked away in the same way.
But ironically, many of these same stories end up putting a high value on the very things we take for granted in the everyday lives that escapism offers release from.
