I haven't seen TLJ and I never will. I also have never seen the 3rd film of the prequels, what's it called? Dude Where's My Deathstar? By the time I had watched the second prequel I was so disillusioned that I decided to watch the third on dvd. Then the Vader "Noooooooooo" memes appeared and I thought "Nope."
Similarly, after Force Awakens, I thought I would read some reviews of TLJ first and it was clear from them that the rot had set in. So I am done with the Franchise, mostly because it so clearly IS a franchise now and not a labour of love. I say this as someone who was such a fan originally that I even defended Ewok Adventure: Caravan of Courage to the naysayers.
So in my world the Star Wars universe is made up of the original trilogy, including RotJ. For prequels I have the Han Solo at Star's end books and for a sequel, and S***t's and giggles, I include the Splinter in the Minds Eye book. I like to think that Luke and Leia knew that they were siblings at that point, but just didn't care and went ahead with the steamy snogging.
