I loved Annihilation and it's sequels, not knowing what I was getting into. I would never have come up with those stories. And a one to one translation of the text to screen would have left us without an interesting movie on its own right.
its not like you're writing a story for yourself.
But yes you're right, some people are probably seeking that in their media consumption.
For example, we could tap the federal Strategic Actor Reserve, or import actors from actor-rich countries such as France and Belgium.
There's a shortage of actors that you can star in movies to sell enough tickets to justify making $200m movies that have traditionally been the backbone of studio profits.
The studios probably killed themselves going all-in balls-to-the wall on making the exact same blockbuster movie 12 times a year, every year, for 25 years straight.
It is a refreshing breath of relief to see all the Indie stuff absolutely killing it as of late, and the Action Hero movies consistently underperforming studio expectations by a mile.
Armies of wanna-be actors and actresses, but also ie screenwriters. We only see publicly the result of many consecutive layers of filters/funnels.
