I agree with JBroadway. Of course, this is just my real life experience, but people continue to talk about Star Wars. It comes up in conversation, it’s referenced, people have opinions. With Harry Potter, people talk about it in past tense with a slight tinge of, “Oh yeah, I was really into that when I was younger.”
I completely forgot Fantastic Beasts ever happened, and Cursed Child is great, but I don’t think it’s going to make much of an impact on the legacy in the long run.
Disney, for better or for worse, has kept Star Wars alive and thriving in the zeitgeist. They opened Star Wars lands in their theme parks in 2019, for God’s sake.
I also agree with thedrybandit, not sure how the magic of the show would translate on screen. It would certainly flatten special effects a lot.
I am big. It’s the REVIVALS that got small.
