Nah, not really.
I get why a studio would panic. They have shareholders and their own jobs to worry about. All we worry about is time and a bit of money if a movie isn't good. So I get why if it seems like youre going down the wrong path to try and course correct. Very true that fans are going to see the movie no matter what, but I understand trying to change thing to reach a wider audience. And I also don't think it happens that often. At least at non WB studios
I'm not saying that it's not a problem but not one of the biggest.
The bigger problem to me is why they keep making these weird, quality questionable movies that don't play into any public desire. Why make a $150 mill Godzilla movie where he barely shows up? Why make a Batman and Superman movie where neither are that likable? Why make a $200 mill movie based on The Mummy. That's what I don't get and where I can't even rationalize that.
