What has actually happened is that fans have defined the story and mythology themselves based on the films we have. Lucas himself never had that story mapped out, which is why he didn't keep the sense of it throughout his changes and new films.
Now fans of the 6-part epic really have to struggle to make sense of the whole story and fitting it to the extended universe that has developed based on the OOT.
It's really gutted me, if I'm honest.
I'm sharing, people...
