Star Wars was three movies in the 1970s and 1980s. The idea that they are now to be some sort of eternal, perpetual universe of content is pretty insane if you think about it, and this really is a new way of thinking. For the most part people create their own stuff that is reflective of their times, it is enjoyed by people of their times, and then it gets discarded unless it is truly, truly, truly great (like, Shakespeare or Beethoven tier great). George Lucas made films that were reflective of the times they were made, they were popular... and that's it. The fact is we don't need new Star Wars, we never did, and the fact that Disney made such a hash of it is proof of that. Even the prequels were largely unnecessary.
