In praise of Linn Ullman's essay/story about life with her famous father

Linn Ullman has a piece in the New Yorker that does not seem to be fiction in any conventional sense but more of a memoir-essay written with literary techniques most often associated with fiction: scenes, back story, jumps back in time, precision of detail, insight into personality, sensibility - a fine piece of writing however we categorize it, and the defining lines between fiction and nonfiction may already be obliterated or at least obscure. Yes, Linn Ullman is the daughter of world-famous parents, Liv Ullman and Ingmar Bergman. Her parents never married,; Linn is, as this essay notes, the youngest of his 9 ?) children, and Bergman had 6(?) wives, including one after Linn's birth. In this essay (as I will call it for convenience of reference) Ullman examines her relationship over decades with her famous and famously difficult father; obviously much of our interest as readers comes from our insight into the private life of Bergman, but that's not the whole of it. In fact, I'm not sure there's anything new in what she reveals of his personality - protective of his privacy, enjoying his isolation on the Baltic island, devoted to his work, extremely punctilious, a bit of an autocrat with his family, wealthy though never extravagant, and a true connoisseur of cinema (he refused to watch digital films and had on staff a full-time projectionist; the family would gather daily at 3 - actually, 10 minutes earlier to provide Time for the Eyes to Adjust (Ullman's title). These details aside, it's heartening to see that IB was close to all of his children tright through to the end of his life, w/ perhaps particular affection for Linn U., his youngest, and a prominent Norwegian novelist in her own right. This essay is notable for Ullman's account of her visits over the years to her famous yet reclusive father, of the warmth and understanding between them - never sentimentalized - and of his gradual mental decline, all told with efficiency and precision. Obviously Ullman could get a major book contract for a tell-all autobiography with  detail about both of her parents (her mother has written a memoir), but this piece makes me think she has no desire to pursue that course - she tells her story with such concision here; what's told in a single essay would be tedious and probably salacious if drawn out to book length.
