I don't like it when a character's race is changed to push DEI, or some other agenda and just ended up being a prime example of tokenism.
I really don't like it when characters are changed for absolutely no reason other than being a clear excuse of tokenism.
There are MANY bad examples of raced changed characters that are deemed by many as bad representations of the original characters. For starters, we have The Little Mermaid movie in 2023, which RIGHT FROM THE GET GO had been under controversy for portraying Ariel, a character who's widely considered white be portrayed by Halle Lynn Bailey. There's also the 2025 Snow White movie, where, again, face similar inital criticism for potraying Snow White, who's been described to have skin as white as the snow be portrayed by Rachel Anne Zegler. Also, we can't forget the upcoming potrayal of Severus Snape in HBO's upcoming Harry Potter television series who, while, haven't even been released yet, already face MASSIVE criticism for casting Paapa Kwaakye Essiedu as the head of the Slytherin House. And of course, many more I couldn't mention.
That said, there are some great examples of the best race changed character is Nick Fury. He was originally white in the Marvel Comic, but Samuel L. Jackson did such a good job acting that it gave the character a new image in everyone's mind. It also helps that Nick Fury's race swap was done after Marvel's Ultimate Comics line in the early 2000s became so popular where there, Nick Fury WAS portrayed as a black man and continued to be potrayed as black in the Marvel universe ever since. Nowadays, if you tell newer Marvel fans who only know the character from the MCU movies, I can almost guarantee that they'll be shocked when you say that Nick Fury was originally white.
There's also what I'd consider a good a good race changed characters, too, like Domino in Deadpool 2. Originally, Domino has always been portrayed as white, and I mean that literally, her skin is literally white with only a considerable size black spot on her left eye area. But in Deadpool 2, when Zazie Olivia Beetz played the role, her acting was quite good, and I'd say most people would say she's an okay or good good job portraying Domino in Deadpool 2.
In my opinion, those two characters are two out of maybe only a few characters whose race got changed and are handled in a good way. Not just some obvious DEI plant that ended up becoming a prime example of tokenism.
