Ghostbusters needed to show that black women can be scientists too

When the Ghostbusters reboot was announced, it was hailed as a victory for feminism. The film stars Leslie Jones, Kate McKinnon, Kristen Wiig and Melissa McCarthy as four women who save the world from an onslaught of ghosts, and I enjoyed it when I saw it. But it bothered me that while all the white women are cast as scientists, the only black actor, Jones, instead portrays a subway worker.
