Yes - there's a few whites in it but its 99% black. Liberal hypocrites say all-white movies are racist but all-black movies are a way to fight racism!!!
The irony of the OP is that no one was whining like you when the lord of the rings came out with 6 straight movies and there wasnt a Black person in any of them.
This reminds me of a controversy over in videogame-land. A game recently came out set in a realistic depiction of medieval Bohemia and SJWs are mad and calling it racist and sexist for not having any black people in it and for not having any female heroes.
But I digress. Glad you guys got yourselves a superhero movie. I can't think of any reason to be upset about it.
