Brandon Sanderson has talked about how a screenwriter wrote a script for one of his books but when he read it, everything was changed. It had new characters, a new love interest, and even the world itself was altered extensively. Sanderson said that Hollywood writers have in mind what THEY want to write and simply use the shell of infinitely more popular works to do it. We see this over and over.
What I don't understand is how Hollywood cannot grasp why this would tick people off.
The thing about Snow White in particular is that they could have updated some of the more "problematic" elements without much fuss if they had been even remotely subtle and respectful about it. Instead they had to scream to the heavens that the original was trash and that their own version was only related on a superficial level.
I can only assume it's the bubble these people live in, where everyone they know thinks the same way. Kind of what we're seeing with game developers, too.
On top of that, many of these writers aren't nearly as talented as they think they are, which is probably why they can't find success with their own original material. Forget Snow White being a remake, even if it wasn't the writing would be terrible. For example, it's supposed to be about female empowerment but their Snow White is a princess who literally does nothing to earn her place or her victory. Even feminists have pointed out how that makes no sense.
