I like when media have diversity.
Take Black Panther for example... a movie where the lead roles were inevitably going to be dominated by black actors, and they still managed to put white guys in a couple decent-sized roles. The diversity made that movie more accessible to a wider audience.
I once had a coworker who said to me "all white people look the same," and while I don't share his sentiment, it's important that characters are distinguishable to a wide audience. Including a variety of races is like the easiest way to ensure characters are distinguishable.
