Allowing the victims to speak their truth is invaluable and thus is an incredibly important service the filmmakers have done buuuutt ... there should be a different category for these than, 'documentary'. This film, the R. Kelly one, the Michael Jackson one are all just basically 5 hour long victim impact statements. To me the term, 'documentary', means someone does the arduous work of zooming out through research research research and more research and then more documents and more research and then presents the facts without an emotional heavy hand leaning one way or the other. It documents. Victim impact statements are one of the most important parts of any story but I'm not sure it should be considered the whole story or 5 hours of it.
Overall though, this is impactful and definitely worth watching.
