Will this repetitive juvenile nonsense ever end?
Even if this installment were total garbage it would still make the better part of a billion dollars. And as long as the movies keep making money they'll keep cranking them out.
Long answer:
Domestic box office take of Star Wars films:
Star Wars: $445 million
Empire Strikes Back: $276 million
Return of the Jedi: $297 million
Phantom Menace: $431 million
Attack of the Clones; $302 million
Revenge of the Sith: $380 million
Force Awakens: $936 million
Rogue One: $532 million
Double the numbers to take into account worldwide box office. Triple them (at least) for merchandising.
Short answer:
No.
No time soon. Force Awakens was over 2 billion dollars worldwide from the box office. The franchise isn’t going anywhere, the new one may possibly exceed one billion as well. Yeah, they are a stupid concept, and always have been, but I can enjoy them more than a lot out there.
