Well it was a terrible mistake to take a known property and change the race of the characters just to be different. That is off putting to the people you were hoping to attract to the show who were established fans, the fans you wanted when you bought the property and kept the name the same.
Hollywood people really have to fight hard to get out of the bubble they are trapped in. respect the source material.
It's not about respecting the source material; it's about trying to straddle the fence and losing both sides in the process.
If she had been able to make the entire cast black and truly transform WiT into a black franchise, she would have gotten some of the same support from the black community as the people who are turning out in droves to support
Black Panther despite not even being superhero movie fans. Purely because it demonstrates a revolutionary effort at increased black representation in blockbuster film.
But instead, the movie is not exciting black people because its leads are all white and biracial characters (Gugu, Pine, and Storm Reid). And it's still getting the same backlash from white people for not being entirely white as Fantastic 4 did.
So it's losing on both sides.
The problem was not changing the race; it was not going far enough. Ava's a black director, and she's woke: You know she's not settling for directing no 100% lily-white films to "respect the source material".
But the compromise she had to settle for to get this made is not going to get her the support she hoped for.
