@Richard_Littler Unfortunately a well wrapped story sells better and is warmer regarded then a new thing out of a shiny box.
Where would you place Bladerunner 2049? It's original content but for a very old movie, so it feels rebooty while being technically the next entry in the series.
I have no idea about Wonka but I do think the modern capabilities of movie and graphics lends themselves to wanting a remake of old stories. This has always happened, ever since Tolkien showed the world how to do fantasy (big, world changing) - every other fantasy story must lower its head to lotr in some way (even the so claimed opposite sides of fantasy, as they have LotR to reflect themselves off of).
The brand new content is the largely user created, free to publish stuff, like all the indy writers/ebooks, because access to publishing is so easy now, and to a smaller degree the shows being made on streaming services, who can fork out money to see how a short season goes before dedicating to a bigger budget. I'm thinking like Bojack Horseman and Big Mouth (not to promote Netflix, but they are my fav adult cartoons).
The new stories on a grand scale (like Wonka's presence but by an unknown individual) aren't sure hits, so they don't get the budget to advertise as well, so reach is very limited.
As an example, Hoyts Australia buys "packages" of movies, say they want an Aussie movie, but it'll be 1 movie in a packet with 9 usa movie. The chance for that Australian movie to shine is minimised by the skew in country of origin (plus people seem to think Aussie stories suck, or are full of kangaroos, spider, and death).
Interesting topic though! It's a good chew, always has been, and it leads to the next:
Is something good just because it's totally original? I mean, I still love Beowulf, and every one eats up historical fiction, very old stories. But "The Great" is a brilliant show, which they admit is "sometimes" based on the truth.
Ty, my 2 cents, take as you like =)
