i always found it weird, pre the MCU marvel films (sony responsible for spiderman) had been a bit of a joke....and star wars was a licence to print money...but then we get 2-3 marvel films a year for 15 years and i would say more wins than losses....and we get 5...average and disjointed star wars films
2-3 is too many and you can see the marvel burn out....but i have no idea why we havent seen 1-2 star wars movies every year...they have thousands of years of EU the can blunder for material (KotOR trilogy would be an easy one for me), we should have had trilogy followed by a year or two of stand alone like R1 and Solo followed by the next trilogy
I think the simple answer is they flubbed hard. The original plan was regular star wars films
https://en.wikipedia.org/wiki/Star_Wars (see other potential projects)
They started off with a new trilogy but rather than have a creative vision but they hired a creative hack who had never finished off anything well in his life. The JJ Abrams mystery box is also a terrible terrible story telling fram if you want a begining, middle and end whilst finish satifisfactorially.
This is Abrams approach,
Who's Snoke? who cares
Why does Maz have the youngling killer 3000? Who cares
Why does C3PO have a red leg? Who cares
Who's Rey's parents? No important
Why is Luke on the island? *shrugs*
Potentially interesting story setup but with a clear answer the series run onto Rian Johnson playing telephone. Johnson answers some of these questions or simply shows as much attention to it as Abrrams did. But his decisions are incredibly divisive (I think he made a great film).
To fill the gap they create Rogue One which is a production mess Edwards the director has pretty much disowned it. People love it (I think its good but not great) but its really Star Wars for Star Wars nerds. The story is there for something interesting to explore and they pretty much do that in Andor (watch Andor).
TLJ doesn't flop by any stretch but loads are unsatisfied and in terms of later projects in start the studio second guessing they've hired Johnson for a trilogy but the neckbeards hate is strong.
Then their real first misstep is Solo, no one wants a Han Solo original story. Especially one which basically serves to show how he gets his stuff like his name. The movie also fails because it gives Han a love interest and we all know thats doomed because it not Leia. Its fine but no one really cares for it. Its also a production mess they fire Phil Lord and Chris Miller but bring in Ron Howard as a safe pair of hands.
Terroview turns in a script which the studio hates but the schedule must stay. They rehire hack JJ Abrams who unsurprisingly has no idea how to finish the story he started, he writes partially to cater for neckbeards but the studio lost those guys so instead they manage to also **** off those who love TLJ satisfying no one. It flops relative to its insane budget.
Its December 2019 in 5 months the studio shut everything down whilst they rethink things.
They'll get there but yeah the answer is hiring JJ Abrams and theres a reason he's been hired for **** all since.
Edwards, Gilroy, Johnson, Lord & Miller have all done interesting stuff since.
Howard less so since but some of his movies are all time greats.
