Aquaman 2 May Be Heading Toward A Worse Box Office Crash Than The Marvels
Aquaman 2 box office prediction suggests The Lost Kingdom is heading for a worse fate than The Marvels when it premieres in December.gamerant.com
TLDR: Aquaman is tracking even worse than the Marvels. It too had an initial film that grossed over a billion. I think we can safely say that the superhero movie bubble has burst.
I don't buy the idea of Superhero fatigue, I think it's alot more then that, this wasn't fate, and look at how well Into the Spiderverse and GotG 3 did.
The money is still there, it's just that they have to cut the waste and cut the budgets like Sony did except for the biggest movies.
Spiderman was animated and cheap and you know Spiderman.
GotG3 was essentially the last phase 3 movie popular characters.
