There is no room for ambiguity in this documentary. Ava DuVernay has a message to impart and she wants to make damn sure that you get it. While she never resorts to Michael Moore narration or Errol Morris recreations, the bravura editing by Spencer Averick (obviously under DuVernay's direction) makes damn sure that nothing is lost on anyone. A single cut can bridge 150 years and help us to better understand how we got into this mess in the first place. Sure it's unsubtle, that's deliberate. DuVernay knows how important it is to pick the right tool for the job. If you want to carve the statue of David, you use a chisel. If you want to tear down the Prison Industrial Complex, you use a sledge hammer. I'm glad that this film is on Netflix so that it can be seen by as many people as possible because this is a documentary for right now.
