This is really a successor to the one-man, low-budget productions of Oscar Micheaux in the 1920's and 1930's, rather than one of the blaxploitation movies of the 1960's and 1970's.
Blaxploitation movies were urban. They were action movies with karate, knife, and gun fights; they pitted black heroes (sometimes good guys but often criminals themselves) against bad white guys (usually politicians and cops). They had pounding rhythm and blues scores and pimp style, and most of them were produced by major film studios, though on relatively small budgets.
The black-audience shoestring independent productions of Micheaux and his colleagues, on the other hand, most frequently had rural or small-town settings. Their characters were rarely involved in crime, and there was minimal violence. There was also little conflict between blacks and whites; the conflict was intraracial, and the movies usually had a religious, moral, or social message.
Under either title, "Black Hooker" or "Street Sisters," this movie markets itself as a blaxploitation movie, but its main elements are all from the earlier genre. It's the drama of a conflicted family, with a grandfather who is a crazed preacher; a grandmother who is the earthy family peacemaker; their daughter, the title character, who is more like the fallen woman in the earlier films than like the flashy, assertive whores of the later ones; and the daughter's son who is light enough to pass for white (and passing is a common theme of the earlier movies).
It's also, unfortunately, just as clumsily plotted and directed as the Micheaux movies.
