Writer/director Aleshea Harris adapts her acclaimed play of the same name into the assured feature film Is God Is (B) about twins played by Kara Young and Mallori Johnson, both in riveting performances, traveling cross-country from the Deep Dirty South to California chic upon request of their mom (Vivica A. Fox) to exact revenge on their estranged dad (Sterling K. Brown). The film contains gritty drama fused with a campy spaghetti western violent sensibility akin to Thelma & Louise by way of the Kill Bill saga. Harris marches to the beat of her own drumline with her two unlikely protagonists often speaking in knowing telepathy to one another, rendered in subtitle fragments. Encounters with larger-than-life adversaries make for some jaw-dropping episodes while the women, disfigured in infancy, alternately grapple with impulses to forgive or fight. These are characters we haven’t seen on screen before in an unexpected thinking person’s road trip revenge adventure.
