People who reject qualitative artistic appraisal of movies will reject that any such trend exists, and will say that everything is fine by the empirical metric of box office returns. They're missing the point; the reason movies are being made like this is because it's the least risky way to make a movie. Of course box office returns are going to look good, that's the point.
If the problem is simply, "I have to look too hard to find good things," or "ugh, they are making another Minions movie," then, congratulations, you are a hipster. But that's not really a problem, you just have good taste!
But there are great movies still being made. You just have to look fairly hard. The last few years have seen some brilliant films like:
* Everything, Everywhere All At Once
* Nobody Knows I'm Here
* Portrait Of A Woman On Fire
* Argentina, 1985
* The Banshees Of Inisherin
