While they don't care about fans, they do care about two other things: making and losing money. You are right in saying they don't seem to learn the lessons, but at some point a studio can only make so many flops before it can't stay a float. Look at Disney. I saw a headline that they've already hit pause on a number of live action remakes after Snow White, including Tangled.
No one intentionally sets out t make a bad movie that will fail. Well, unless you're Max Bialystock and Leo Bloom in Mel Brooks The Producers were they set out to make the biggest bomb possible so they can take the tax write off in cancelling the production. Hopefully...this is not a Bialystock and Bloom scenario.
Its hardly just here on NarniaFans. Narnia Web it's the same thing ( I'd estimate it's even stronger....mods had to censor a comment in the forum). Scowering Screenrant, Deadline, et all, comments on this news are also overwhelmingly negative and not just from fans of the books, but casual movie goers who are tired of arbitrarily swapping characters. This leaves them with at least a stunning 1 % in favor, which is not what you want for a major motion picture.
And the "original source" for the reporting, Nexus Point News? 100% negative comments.
They already are going against the current by choosing Magician's Nephew, a lesser known book in the mythology, with those same casual fans wondering why they are starting there, and now they have this going against it.
Again, we are just spectulating at this point, but, if I were to guess, I would not consider it out of the realm of possibility that someone from the CS Lewis Company leaked it in order to gauge the fan reactions and then go back to, say producers, or casting directors, or even Gerwig and say, "Look, this is a really bad idea. We gauged the fans and they are overwhelmingly opposed to it." Studio execs think in terms of numbers and charts, and thus, it's not always enough for, say The CS Lewis company, to put it's foot down .Sometimes they need some stats o back it up.
Now, why Nexus Point news, and not say, us or Narnia Web? Again, if I were to guess, if I were with the company, I would probably choose a neutral publication as opposed to a Narnia or CS Lewis oriented one. You can already tell which way the fans would go with Narnia and CSL. Some other site can give you a much stronger sampling.
Again, just my theory .We have no idea what is actually going on, and again this is just the "In Talks" phase.
