From teenage model to upper-crust caterer to domestic doyenne to media-spanning billionaire to scapegoated convict to octogenarian thirst trap enthusiast and Snoop Dogg chum, Martha Stewart has had a life that defies belief, or at least congruity.

It’s an unlikely journey that has been carried out largely in the public eye, which gives R.J. Cutler a particular challenge with his new Netflix documentary, Martha. Maybe there are young viewers who don’t know what Martha Stewart‘s life was before she hosted dinner parties with Snoop. Perhaps there are older audiences who thought that after spending time at the prison misleadingly known as Camp Cupcake, Martha Stewart slunk off into embarrassed obscurity.

Those are probably the 115-minute documentary’s target audiences — people impressed enough to be interested in Martha Stewart, but not curious enough to have traced her course actively. It’s a very, very straightforward and linear documentary in which the actual revelations are limited more by your awareness than anything else.

In lieu of revelations, though, what keeps Martha engaging is watching Cutler thrust and parry with his subject. The prolific documentarian has done films on the likes of Anna Wintour and Dick Cheney, so he knows from prickly stars, and in Martha Stewart he has a heroine with enough power and well-earned don’t-give-a-f**k that she’ll only say exactly what she wants to say in the context that she wants to say it. Icy when she wants to be, selectively candid when it suits her purposes, Stewart makes Martha into almost a collaboration: half the story she wants to tell and half the degree to which Cutler buys that story. And the latter, much more than the completely bland biographical trappings and rote formal approach, is entertaining.

Cutler has pushed the spotlight exclusively onto Stewart. Although he’s conducted many new interviews for the documentary, with friends and co-workers and family and even a few adversaries, only Stewart gets the on-screen talking head treatment. Everybody else gets to give their feedback in audio-only conversations that have to take their place behind footage of Martha through the years, as well as the current access Stewart gave production to what seems to have been mostly her lavish Turkey Hill farmhouse.

Those “access” scenes, in which Stewart goes about her business without acknowledging the camera, illustrate her general approach to the documentary, which I could sum up as “I’m prepared to give you my time, but mostly as it’s convenient to me.”

At 83 and still busier than almost any human on the globe, Stewart needs this documentary less than the documentary needs her, and she absolutely knows it. Cutler tries to draw her out and includes himself pushing Stewart on certain points, like the difference between her husband’s affair, which still angers her, and her own contemporaneous infidelity. Whenever possible, Stewart tries to absent herself from being an active part of the stickier conversations by handing off correspondences and her diary from prison, letting Cutler do what he wants with those semi-revealing documents.

“Take it out of the letters,” she instructs him after the dead-ended chat about the end of her marriage, adding that she simply doesn’t revel in self-pity.

And Cutler tries, getting a voiceover actor to read those letters and diary entries and filling in visual gaps with unremarkable still illustrations.

Just as Stewart makes Cutler fill in certain gaps, the director makes viewers read between the lines frequently. In the back-and-forth about their affairs, he mentions speaking with Andy, her ex, but Andy is never heard in the documentary. Take it as you will. And take it as you will that she blames prducer Mark Burnett for not understanding her brand in her post-prison daytime show — which may or may not explain Burnett’s absence, as well as the decision to treat The Martha Stewart Show as a fleeting disaster (it actually ran 1,162 episodes over seven seasons) and to pretend that The Apprentice: Martha Stewart never existed. The gaps and exclusions are particularly visible in the post-prison part of her life, which can be summed up as, “Everything was bad and then she roasted Justin Bieber and everything was good.”

Occasionally, Stewart gives the impression that she’s let her protective veneer slip, like when she says of the New York Post reporter covering her trial: “She’s dead now, thank goodness. Nobody has to put up with that crap that she was writing.” But that’s not letting anything slip. It’s pure and calculated and utterly cutthroat. More frequently when Stewart wants to show contempt, she rolls her eyes or stares in Cutler’s direction waiting for him to move on. That’s evisceration enough.

Stewart isn’t a producer on Martha, and I’m sure there are things here she probably would have preferred not to bother with again at all. But at the same time, you can sense that either she’s steering the theme of the documentary or she’s giving Cutler what he needs for his own clear theme. Throughout the first half, her desire for perfection is mentioned over and over again and, by the end, she pauses and summarizes her life’s course with, “I think imperfection is something that you can deal with.”

Seeing her interact with Cutler and with her staff, there’s no indication that she has set aside her exacting standards. Instead, she’s found a calculatedly imperfect version of herself that people like, and she’s perfected that. It is, as she might put it, a good thing.
