On the other hand, aside from the massive big-budget hits of Barbie and Mario, there were also a number of mid-budget films that did very well: John Wick 4, Sound of Freedom, Five Nights at Freddy's, Cocaine Bear and M3GAN all exceeded expectations.
So it's hard to interpret this as the "middle class" of movies disappearing. I'd say it's the opposite, in fact. People have gotten sick of the big-budget crap that follows the same formula (note how most of those bombs are superhero movies). It's really the big-budget films that are falling apart.
