George Lucas probably had no idea that Star Wars
, his story about a moisture farmer going on an adventure, would change the course of storytelling. Memorable characters sure help set it apart from other science fiction, but Harvard Law professor Cass Sunstein has good idea as to why it's such a global phenomenon. The original trilogy, he states, has something in it for everyone in that it tackles some very human problems: redemption, authoritarianism, and the appeal of darkness. Cass Sunstein’s research is cited in The Influential Mind: What the Brain Reveals about Our Power to Change Others by Tali Sharot.
