Dan Reed’s four-hour Michael Jackson documentary “Leaving Neverland,” which details the allegations of child sex abuse against Jackson by two men, premiered at Sundance Friday.

The Michael Jackson estate issued a statement decrying the doc, calling it “the kind of tabloid character assassination Michael Jackson endured in life, and now in death.” A few protesters also showed up at the screening at the Egyptian theater in Park City, Utah, and the doc’s IMDB page was vandalized by fans.

Here, Variety senior film writer Matt Donnelly breaks down the doc.
