The Vow is an American true crime documentary series directed by Jehane Noujaim and Karim Amer that revolves around the cult NXIVM and its leader Keith Raniere.

[11] The second season of the series focuses on Raniere's trial and takes a continued look inside his inner circle and at ongoing supporters through interviews with co-founder Nancy Salzman and her daughter, Michelle Salzman, former NXIVM members Karen Unterreiner, Isabella Constantino and Verónica Jaspeado, New York Post journalist Emily Saul, lead prosecutor Moira Kim Penza, defense attorney Marc Agnifilo and supporters Nicki Clyne, Marc Elliot, Michele Hatchette, and Eduardo Aunsolo.

[18] Noujaim wanted to interview all involved in NXIVM including its founder Nancy Salzman, who took a year to decide to participate in the series, to show a 360-view of an "eco-system of manipulation".

[22][23] Production on the series began in 2017, initially focusing on Sarah Edmondson, Mark Vicente, Bonnie Piesse, Anthony Ames, and Catherine Oxenberg as a way to document their escape from NXIVM as they were fearful of being sued by Clare Bronfman, and wanted to protect themselves by having it taped.

[34] For the first season, Noujaim and Amer wanted the series to unfold in a "indoctrination" way stating: "This is why it is not until the penultimate episode, “The Wound,” that we share the most gut-wrenching concepts and where the inner circle were being led.

The website's critics consensus reads, "Though The Vow's scope at times exceeds its reach, its empathetic approach to unpacking NXIVM's manipulations and the consequences thereof make for necessary, difficult viewing.

In a positive review, Adrian Horton of The Guardian wrote that "as a portrait of manipulation and, in particular, the masking of female abuse through self-effacement, the series is darkly compelling, unnerving in a way that’s hard to shake," but conceded "[it] deceptively muddies the timeline of the group’s development.

Club's Ashley Ray-Harris was less impressed and attributed the "wasted nine hours" and selective content to the (former NXIVM) filmmakers' desire to "get ahead of the curve with their own narrative.

The website's critics consensus states, "While this second installment of The Vow wouldn't have enough meat on the bone to sustain itself as a self-contained docuseries, it succeeds as an introspective supplement that deepens what came before.
