Come December, the fact that IX is being advertised as "the end of the saga" is going to outweigh almost all TLJ ill-will. We're already seeing the effects of that after just one teaser trailer. It's going to be a can't-miss blockbuster event with virtually no competition. It's not just the end of the sequel trilogy, it's the end of all nine movies, and they're only going to underline that fact more and more. Also, if it's good, and everyone and their dog is raving about it, are there really people who would STILL sit it out because of TLJ? I highly doubt it. Again, we're not talking about opening weekend, we're talking about the entire run. Endgame will have an insane opening weekend - probably the biggest of all time, and I seriously doubt IX's opening weekend will top it - but Endgame just has too much competition over the next six weeks or so to beat IX in the long run. Now, if IX sucks - and it very well could - my argument is of course moot. I'm assuming Abrams is going to come through, though.
