Why My Struggle Book 6 should have been cut by half

As noted yesterday I am skipping over the sections on Hitler's life and writings in My Struggle: Book 6, which represent about 100 pp (beginning at about the 40% mark) though it's impossible to know for sure thanks to the ridiculous pagination system on Kindle (what the hell is Loc 4401?). That said, this final volume of Karl Ove Knausgaard's novel has taken a strange turn. After a long opening section focused on the attempts of KOK's uncle Gunnar to sue the publisher and stop publication of the very work that we are reading, and with much anxiety and gnashing of teeth by KOK, along w/ many detailed scenes of his attentive parenting of 3 children while his wife/their mom Linda is away, KOK begins offering detailed analysis of a poem by Celan, then of Hitler's writings, and then onto other literary and sociological topics. On one level, just about everything he has to say is intelligent and quirky and probably worth reading w/ more attention that I've been giving it - but in all honesty I don't really want to read a series of essays; these insights or epiphanies to use Joyce's term don't rise out of the narrative flow of the the work - as do Joyce's, Proust's, Updike, to name 3 writers known for narrative styles rich w/ authorial insight and observation. Rather, KOK seems to have steered away from his narrative, hijacked his own novel, and turned it into an essay collection. The two (I think) works KOK has published in the wake of My Struggle are essay collections, so it does seem as if he's no longer interested in fiction per se nor in telling his own life story in particular - well and good, but he's done a disservice to the many readers who have followed his narrative toward the end. This final volume has become an indulgence and in my view should have been cut by half, at least, and let the essay-like writing find its own course. I'm still curious as to how this novel "wraps" and will keep reading, but with a wary eye and with a sense of looming disappointment.
