I thought it was pretty accurate and unbiased, they definitely made an extensive investigation of the topic and it's good to watch actual witnesses of what happened during those dark days.
I stopped watching at the part where they were talking how Rollingstone was her cover and her follow up cover was the Esquire shoot in which she's damn near naked but failed to notice how that's in 2003 and definitely not her 2nd phootshoot in her career.
