Los Angeles Times critic
Lorraine Ali wrote that the series is "a comprehensive, convincing and ultimately devastating documentary that threatens to burn what's left of [Allen's] career and legacy to the ground."
Dorothy Rabinowitz's review in
The Wall Street Journal describes it as "an extraordinarily detailed investigative work". ''
Variety's'' review said that Dylan speaking out "represents for her, one might hope, a closing of this chapter and, perhaps, a chance to start anew". Brian Lowry of
CNN wrote, "despite the painstaking research, viewers might come away not entirely sure what they 'know,' as opposed to what they believe", but said that "even a generous reading of Allen's behavior, however, casts him in a troubling light." Nick Allen of
RogerEbert.com gave the docuseries three and a half out of four stars, and wrote that "It is the exact type of expansive analysis that this horrific Hollywood saga has needed, and I urge both those who believe and don't believe the Farrows' side of the story to watch it." Eric Deggans of
NPR wrote that the series holds Allen's "past behavior up to modern sensibilities in a way that makes him look terrible", but that "questions will remain about what may be left out, absent the direct participation of the man accused of so much." A
Globe and Mail reviewer wrote that viewers get "a complex and sometimes confusing picture of the family dynamic", with Mia Farrow "controlling" the narrative, and that there is an "attempted evisceration of Allen's denials, but some of it is unsupported." He called the series "incomplete". The Dutch newspaper
De Volkskrant asserted that anything that could exonerate Allen was "systematically pushed aside", while
NRC Handelsblad concluded that the miniseries is partial to the point of being "blunt propaganda" by "activist" directors, "void of all pretense of journalistic integrity". Some of the coverage focused on the lack of involvement of two of Farrow's adopted children,
Moses Farrow and
Soon-Yi Previn, who have offered accounts of their childhood that were critical of Mia Farrow.
Screen Rant critic Lindsey Deroche noted that Moses declined to participate, but, still, "in order for the HBO documentary series to appear objective ... it needs to include every voice in the long history of this scandal...For
Allen v. Farrow to be as effective as possible, it needs to appear objective and comprehensive—which requires including the perspective of Moses Farrow." ==Awards and nominations==
