Isn't this because the mid range is going straight into the streaming services, rather than through (an I assume expensive) distribution process into theaters?
Theater going is expensive (I think it's expensive), the alternatives are "pretty good", so that impacts overall theater presence.
Having a "block buster" that can justify the expense of marketing and distributing to the now weaker theater market seems like a prudent thing for the studios and it's just part of the current reality of entertainment.
I know I don't see many movies in the theater. I don't know if I've seen anything since Top Gun. I was hoping to see Dune 2, but it's delayed. I will be seeing the Ferrari bio-pic, simply because I'm a Mann nut. Otherwise, we rented Barbie. We rented GoG3, we'll be renting Oppenheimer.
And whatever other random stuff I sleep through from Netflix.
