They tried, but ultimately failed. There were like 11,000 reviews when the audience score started going up, but that number is up to 33,000+ now and the audience score has leveled out at 51%. That's eerily similar to Solo and Last Jedi.
I'd take
intlzncster's advice - make a good movie - and add, maybe try not to intentionally alienate your core demographic.
The box office projections have been dropping for weeks. Last I saw, they were only projecting an opening weekend of $80 million or less. Also heard they filmed two different endings for Endgame - one with and one without Captain Marvel, considering how this movie is received. Will be interesting to see how it turns out.
On the Star Wars side of things, the fan reaction has clearly had an impact on their plans going forward. Maybe the Marvel side of the house can get out in front of this. I tend to doubt it.
