“Bad Hair” is Justin Simien’s sophomore effort, following the critically-acclaimed “Dear White People.” It also opened the midnight section at this year’s Sundance Film Festival. This blend of the socio-political and horror falls mostly flat in its attempt to both provoke and entertain. Set in 1989 L.A., the movie revolves around Anna (Elle Lorraine), working as an assistant on the music video show, “Culture.” She desperately wants a promotion, but sees her dreams evaporate when her boss leaves the company, replaced by Zora (Vanessa Williams, miscast), who wants to revamp the business by, gulp, adhering to white culture.
