I am convinced you're mostly right and the sausage machine is set to autopilot most of the time. I mean just look at all those Hallmark romance films and their knock-offs on other networks... You can find like 4 new ones a day nowadays, just change the job title and actors, poof, whole new movie with little to no re-writes.
But there are still good filmmakers out there with original ideas, just once in a blue moon. Even in major properties like the Star Wars franchise there are rare gems to be found... Those Sequels were trash but did you see 2016's Rogue One? I literally judge that to be the best movie of the entire franchise, even over Episodes 4, 5, & 3! It had the most real drama by far.
Some say Chris Nolan makes great movies this century but I think he's a bit overrated... Still got a nice style, however.
I'm actually quite surprised how good a few movies are that a B-list actress named Samara Weaving keeps finding herself in. Go check out "Ready or Not" from 2019 to see what I mean. Just wow. Mahem and Guns Akimbo were also brilliant. She was also Bill & Ted's daughter in B&T3... She's really great a picking roles and practically any movie she's in should be a cult classic.
One things for sure; the better the movie, the less the mainstream seems to talk about it. This is the root of your problem.
Enjoy!
