What's the appeal ? Star wars is finished, Marvel side of things is never going to reach the heights of the last decade, the streaming bubble is going to burst because every company wants a piece of the pie, so what is there to make it appealing in the future ?
Streaming industry is only going to get bigger, so the pie will get bigger. Star Wars and Marvel isn't finished, that brand is too big to let go, they'll keep creating series and films, like the Mandalorian. Cinema's are dying, big TV's are getting cheaper, in 20 years, people will have 100inch TV's playing the latest films from Disney. Don't underestimate Disney Kids as well, parents will pay $12 a month so their kids have a stream of content to watch. Disney will make people money, if people buy at the $75 range, they'll double their money in a couple of years easily.
