UK person here - so excuse any local reference... I remember reading Empire magazine a few years ago: its cover was the "summer of sequels". Superheroes, etc.
But... this was 1989. Franchises aren't new: it might feel like they squeeze everything else out - and for many cinemas that might be sadly true - but there are always enough non-generic films to go to. E.g. "H is for Hawk" was lovely, "Marty Supreme" was great, "Sinners" was stunning. Relatively recently there was "Civil War" (although possibly looking more like documentary as time passes), "The Anniversary" (similar), "Bugonia", etc.
Might also help that the local Cineworld (a multiplex chain) has dropped standard ticket prices to £5 and Imax tickets to £7, which for this family of three means it's cheaper to see a new release at the cinema than as a "home premiere" on streaming. (And, yes, I know wait another few weeks and it's the price of a single ticket.)
So, why not? "Hail Mary" - probably the weakest of everything I've mentioned here - was still pretty enjoyable in imax.
Yes, there's lots of "generic" sequel nonsense, but search out the other stuff. It's there, and if things like "Secret Agent" make money in cinemas, more stuff like that might get made.
