What makes an enduring fandom? From Star Trek and Star Wars, to Harry Potter and Lord of the Rings, what makes a fandom lasting and persisting? Why do some fandoms garner such a huge following, while other fandoms simply fall away? I think there are many factors, but for me, two of the biggest draws are the story and the characters. If those two factors are solid, I think a fandom has a chance of lasting a good long time.
