lacks drama
T.K. Carter as the tragic Gary, Khandi Alexander as the conniving Fran, Clarke Peters & Reg E. Cathey as old-time users make this worth watching. Other than their characterizations the portrayals in this series lack depth. The series lacks the drama and tension of The Wire or Oz, in which many of these actors have also appeared.
I realize this was a "mini-series", but other than Gary, who does the viewer really care about?
Charles S Dutton's semi-narration adds nothing but a sense of "staging."
