Oh I guarantee you have something to say if during a discussion if someone says, if only Andor was as well put together show as she hulk. You aren't the person to just let that slide on by.
Here's where I see it a bit different. Star wars came out in the 70s. It's never had a problem gaining new generations of fans. This "shrinking of original fans" narrative seems to be a Disney manufactured thing. Go back to before Disney purchased lucasfilm. I'm not sure how many star wars events you went to. But in all my comic conventions, toy shows, star wars events like star wars weekends, star wars nights at sporting events... One thing that always amazed me was how many new young fans there always were.
I know it gets poo-pooed a lot around here. But before the sequels I was seeing plenty of kids at my kids Halloween parades as luke, vader, Leia, storm troopers, boba Fett, Jedi... We're talking about generations of kids interested in a nearly 50yr old franchise. I'm not saying you never do anything new. You just don't need to change the fundamentals of star wars in order for it to gain a new audience. Especially when the old audience was stronger than ever before the sequels. The force awakens proves it. If the fan base was at all shrinking, that movie does not hit as hard as it did in my opinion.
