Very well said, hairy_hen, that’s where I am. For me it’s the GOUT. The EU has always been in a provisional category for me, some were good enough for me to almost accept as canon while others I rejected. As Dominic says, it can be tricky (or messy, as seriouscoffee says) to describe our own canon but we don’t need to go through a mechanical process - I think we each have a natural sense of what works for us or not.

Official canon is meaningful to those creating official works. By extension it has meaning to those consuming the works. But George Lucas pulled the curtain back on the significance of canon when he created the Special Editions and Disney did it when it dismissed the old EU on a whim. The PT and ST have been sufficiently disappointing that they remain in a provisional category for me.

If I had billions of dollars and bought Lucasfilm, I could tell you all what the official canon is, including my own new PT and ST movies to replace the old ones.
