I'm not a big fan when you don't respect an original work to adapt to today's society by offering what seems to be a quota to be respected to please everyone.
Beyond The Witcher, I see original characters seeing their origins modified. We see female heroes from DC Comics becoming transsexuals, characters becoming black or Asian. It gives too much of an impression of wanting to give oneself a good image to please society.
Instead of modifying characters like we do with Ciri or like MJ in Spider Man which goes from redhead to black, why don't we create new characters? We often talk about changing the ethnicities of well-known heroes, but we never talk about the possibility of creating a new black or LGBT superhero or whatever. The imagination is infinite then instead of wanting to change absolutely everything that is already invented, let's create new characters. Heroes like Black Panther, I ask for more of them because they are so incredible.
Moreover, the opposite effect is never mentioned: How would the world react if Black Panther became white?
Anyway, I look forward to seeing the result even if adaptations of this kind are never a great success. Maybe Netflix will do a better job of it.
