The so-called conclusion of Bolano's Spirit of Science Fiction

Roberto Bolano's posthumously published novel, The Spirit of Science Fiction (2016), doesn't really come to any conclusion, just sputters to a stop. Yesterday I posted on a beautiful chapter toward the end of this novel, which shows us how great Bolano could be at his best and makes us sad that he died, too young, in 2005. He's been much more famous and widely read posthumously than when he was a struggling writer, and it's obvious that he left a lot of work unpublished at his death. I in no way blame his family for trying to publish as much of his work as possible, both for his literary legacy and to draw some income from his estate. But it's also clear that it's wrong to put forward a manuscript like this as a completed novel. It's not; it's obviously something that RB either left unfinished at his death or purposely abandoned, for whatever reason. In the final chapters, as it stands, we learn that the young man who almost never leaves the attic apartment and spends his time writing letters to famous scifi writers is "Robert Bolano" (we would have expected that the narrator, Remo, is the stand-in for Bolano), but I'm not sure this matters except to show us how far RB progressed from those reclusive, formative days (and nights). Then, for the final 20 pp or so, we get what the book labels the Mexican Manifesto, which consists of Remo's account of his visit, with his girlfriend, Laura, to many squalid and sleazy throughout Mexico City; this section is mildly pornographic and just plain distasteful and adds nothing to the novel and, as far as I can see, bears no relationship to any sort of manifesto (which one would expect would set for the literary principles and aspirations of these aspiring writers). This chapter should not have been included, and in fact the publisher should make it clear that this novel itself is an unfinished fragment. It's still worth reading, especially for those who already know RB's work, but not a good introduction for those who don't.
