That's definitely going to factor in, but I think another thing is that I don't think audiences are very into twee superhero movies, and the closest thing to a tone The Marvels seems to have (going from trailers and what people have said that is, I won't see it until it's on Disney+) is "twee".I don't think the Marvels is going to do well, not because of the quality, but it isn't about DUUUUDES being cool. And I don't think it has the appeal of Barbie to overcome that.
It's a pity because neither Captain Marvel nor Spectrum aka also Captain Marvel are particularly twee characters, and Ms Marvel doesn't have to be.
