They definitely took a creative license and ran with it - but in the name of fun and changing things up I’d say why not? Nobody said that sticking to the original canon was necessary, although it depends on the application. Here, I can see that it was fun to portray Éowyn as black. Plus I think that the actress who Peter Jackson cast was just wrong for the role. I do not get the impression that she was a Valkyrie level warrior from the movies. If you’re going to cast an actor based on looks…make sure they can act too.
