Anyone who's angry about this "blackwashing" is either trying to stir shit cause dumbasses always scream whitewashing at everything, or they're misunderstanding this shit really hard.
The only time "-washing" is an issue is when it's erasing an intent with no alternative. When a race actually matters.
The Last Airbender was garbage cause it changed the races of the benders when their race defined huge aspects of their culture. The water benders were brown cause they were meant to be Inuit. The Fire Nation was meant to be Asian. Their race was something integral to their character.
The issues with the recent Witcher shit where they wanted to make Geralt's waifu black is a similar issue. In this case, it was about the setting. The characters are meant to be in a specific setting and the Netflix thing, from what we knew, wasn't changing that setting at all so changing the race didn't make any fucking sense.
On the end of what's acceptable, you got the Deathnote movie. The movie was fucking awful, but the race of the characters being changed wasn't an issue because they clearly were changing the whole thing to be in the west rather than in Japan. Light and L having different races was fine because their race didn't really define them and the setting was drastically changed. What killed that movie was all the other retarded shit they chose to do with it, missing the whole point of the series entirely.
Detective Pikachu is less a "Last Airbender" and more a "Deathnote" situation. Tim's race in the original wasn't of any importance to his character or culture, and this movie is clearly shifting the setting from a vaguely European city as viewed by Japanese people to a more American megacity. Making Tim be mixed or black or whatever doesn't really matter in the grand scheme of things, but it does help him fit into the new setting and tone of the movie much better.
