Seriously tho:
John Boyega - black man.
Daisy Ridley - white woman.
Oscar Isaac - guatemalan/cuban/french.
Gwendoline Christie - white woman.
Lupita N'yongo - black woman.
Maisie Richardson-Sellers - black woman.
Christina Chong - asian woman.
Crystal Clarke - black woman.
The first three people on that list are the leads. The next three people are supporting characters with considerable screen-time, reportedly. Also, the word is that Christie's character is a genderswapped version of the role that Cumberbatch almost landed.
They're going out of their way to make the movie look a little more representative of the audience that will be watching it.
I'm not saying you can't feel unimpressed by the diversity in the cast. I'm saying I'd probably disagree with your level of "meh" about it, though.
Wait, no white men? How am I going to relate?
Come back George, only you can save us now!
