I've been a SW fan since the beginning and I think the franchise is in the best place it's ever been.
Some people will try to spin Solo's soft box office as proof that the brand is losing relevance but I'm relatively certain Episode 9 will end up making more than the TLJ and is pretty much another billion dollar earner.
I just wish Solo was doing better because it's really good.
I think there's many reasons that Solo is performing the way it is at the box office but I won't waste time with that here as there are plenty of ongoing discussions elsewhere. Needless to say, I think many people are simply falling victim to hyperbole about Star Wars, as a whole, if they are going to use the OW of one film to declare the decline of one of America's biggest pop culture franchises. People might actually be singing a slightly different tune if the budget hadn't ballooned due to all the re-shoots. It might've been viewed as a more "modest" Star Wars film.
Episode IX will be fine. Looking forward to IX reminded me of how much I liked the ending of TLJ - it left us in a place where I didn't know what to expect next. As long as the build-up, trailers, marketing, etc. is all handled well, Episode IX should easily hit a billion. I guess the real question is how high will it go? TFA level or TLJ level?
I'm also a bit disappointed in the BO performance of Solo but, as I've said in this thread and others, it's only because I would actually like to see more of Young Han, Young Lando, Qi'ra, etc. but it seems like the projected BO performance might doom any sort of sequel or follow-on film. It's too bad, really... these characters and the actors/actresses that portrayed them really did a phenomenal job.
