"The New Mutants" is a big video hit

[Mutant 77]

Nothing is set in stone in that movies continuity. Colossus in those films had never had a sister, yet here pops up Magik. Even if they did want to stick to "established continuity" (which again does not exist in those movies and wouldn't make sense here simply based on the ages and timelines being wonky), why did they also whitewash Reyes?

1- LOL Colossus never mentioned his sister, because we don't know what happened to her in the original timeline. Neither we know anything about Colossus in the Beginnings Timeline, because "Deadpool Colossus" is an alternate counterpart.

2- The timeline works. Cinematic mutants of the XCM age slower and better than humans. As simple as that.

So no, it's the same Sunspot, 2008 (TNM) and 2023 (DOFP).
They picked two very good actors to play Sunspot and Cecilia in the movie. No racism or political agenda involved at all. Originally, Storm was the "mentor" of the boys, not Cecilia, but for various reasons they changed that. Braga is a great actress, so I'm glad they did that.
