Studios keep not understanding anything at all.
Some of the best Movies etc have happened because it goes against what the "fans" think they wanted.
Some of the bes performances happened because directors choose a unexpected actor.
And studios already have something like that which shows how unreliable it is...its called Test Screenings.
Time and time again Test Screenings have shown that a small test audience and the large General Audience are two different beasts.
Also, at the very least Disney should know how bad it is when halfway through you cater to those who call themself "Fans".
Like, Rise of Skywalker exists and they catered as much as they could to "Fans" and it was bad.
The far easier and better option would be to hold Youtube, Social Media accountable.
That cant be so hard considering how many grifters literally lie and slander studios and cause damage.
Force youtube to demonitize Grifters, force Metacritic etc to take actions against review bombing and the problem solves itself.
A ton of the negativity in fandoms etc exists just because Grifters bet on negativity to get clicks/Money...take those out and the fandoms start to become less toxic.
