They had Nightshade in the trailer. Judging by her photo she's too light/mixed for the role
But in the movie she looks completely different, like a Jada Pinkett lookalike
Judging by her resume she isn't much of an actress, she's a singer. I hope she is really good because there's no reason why an actress like Teyonah Parris or Nicole Beharie couldn't have played this character.
Teyonah Paris/Nichole Breharie wouldn't have played this character because its a relatively small role. The movie has gotten it right on characters for the most part, so I wouldn't get hung on the skin complexion of this character in this movie.
Edit: However, I wouldn't be surprised if there are complaints about how they got the African characters right, but not the African American comic characters
