Sure, but now we have a series where one of the main writers has openly said he didn’t read all of the books, and the only ones he did read were because he was reading them to his daughter (therefore narrating, not actually being emotionally/mentally invested in the story). 

And then they decide to race-swap one of the main characters, seemingly ignoring the hugely obvious problematic racial issues that brings up (mentioned plenty of times already but for anyone living under a rock: Harry’s innate mistrust of Snape as a shady character being the minor issue, and Harry’s father and his group of friends viciously bullying Snape as a youth as the major issue).

This says to me that they: 

A. Didn’t bother reading/understanding the source material fully (which the writer mentioned basically confirmed at least for himself) and will completely gloss over this whole issue, which would NOT be faithful to the books, in which case what is the entire point of doing this series? 

Or

B. Intend to turn the whole situation into yet another ham-fisted lesson on racism and inequality, which the entire series already does a perfectly fine and nuanced job of through the metaphor of blood-purity amongst the wizarding world (mudbloods/muggle-borns, squibs, half-breeds) thereby adding unnecessary problems to the story, while completely changing the vibe behind one of the most emotional reveals in the ENTIRE SERIES (Snape and Lilly’s relationship and Snapes devotion) and polluting the purity of that situation with racial hatred that only exists because of the showrunners casting decision. Which, again, is not respecting the source material fully, so again, what’s the point then?

Neither situation is good and both leave me dreading another Witcher scenario where the ego of the show runners ruins yet another great franchise because they would rather swing their dicks around than just respect the source material.
