Out of all the remakes, Maleficent was probably the worst from a critical perspective. They tried to tie in an origin story that didn't need to be tied. They tried to change the mythos of the original. If any of their remakes were offensive to THEIR own IP it's that one. But with that being said...it made $758+ million worldwide.
And to your point, there are 20 (I thought 19 but we can round up) remakes in the works. We have no idea how many are going to be an exact copy (pretty much like Cinderella) and how many are going to add something (hopefully positive) like The Jungle Book.
For all we know, all 20 of them will have the little twists you prefer.
In my opinion if the movie is good, then who cares if it's a remake?
A Fistful of Dollars, The Thing, The Fly, 12 Monkeys, The Departed...all of them are excellent films and all of them are remakes.
I just think it's a lot easier for people to write off a movie they haven't even seen yet, just because it's a remake. I mean, don't get me wrong, some remakes are terrible, but that's due to execution.
