Let's be honest, getting a good representation of diversity in comic book films have always been a losing struggle. Part of the problem comes in the purist adaptations of iconic comic book characters because the majority of them were created in a time where there was no non-white representation in comic books.

On both fronts. Get to know the awesome ladies of S.H.I.E.L.D!
