While I agree that TLJ left the fandom split, anyone questioning the health of Star Wars should see what happened with SWC.
4-Day passes sold out in about an hour, many single day tickets were gone within a few hours as well. Held at the same exact venue as D23 - which took weeks/months to sell out. If Star Wars fans were really THAT ****ed they wouldn't have gobbled up tickets in record time and at record prices.
And no one wanted Solo. From announcement to release the entire Star Wars community never opened up to the idea. It had nothing to do with TLJ. By the time most people found out it was actually a pretty decent and well done film it was already too late.
