One thing that's become clear to me over the past few years is that it's an oversimplification to refer to "SW fans" as a singular group. We don't all rabidly support everything SW for the sake of it being SW. Makes sense after 40 years of the franchise. I think those distinctions mostly showed up in merchandising and secondary media (cartoons, comics, novels, etc). The movies were the one thing SW fans had in common, however, because they were so few and far between. We grumbled about the Prequels, but we still saw them. Maybe now the movies are slipping as well as a common bond.
I've long since realized that SW is much too big of a media empire for me to be interested in everything - and as a result I get that not everyone is going to like everything that's put out. It's a bit sad to lose that shared interest in everything, but it's also exciting if (and that's a big if) Disney uses it to pursue riskier or more eclectic side projects in the SW universe.
That also might help explain Solo's slow start - Disney misjudging the "SW fans" or taking them for granted. Even then, when we're talking a huge movie, SW fans alone aren't enough to carry it - Disney has to appeal to the low information movie goer (who knows nothing about the troubled production, or political/social commentary brouhaha, or all the Internet movie site buzz, or anything really beyond the fact that it's a SW movie). The only take-away I get from that is that Disney can't just slap a SW label on and expect to print money.
