I have found recommendations of (especially) genre novels from people I don't personally know to be nearly useless. The usual problem is that the work is just
OK but gets talked up like it's great. Sometimes, it's outright bad.
I've got enough past actually-greats—genre and otherwise—to catch up on, I don't need 100 "OMG it's so good!" comments from a dozen sites steering me toward a newer book that turns out to be pretty damn mediocre. That's been the outcome often enough that I just have to ignore those kinds of comments, no matter how frequently-encountered and how unanswered by credible-seeming naysayers they go—those aspects, maddeningly, don't seem to correlate with them being more likely to be good advice on what to read next.
IDK what the deal is, though I suspect it's actually multiple forms of difference in judgement of fiction and expectations for how one frames a recommendation, which have different causes but the same outcome.
Like, I basically need a top-ten in-genre books and a top-ten (dealer's choice) works outside that genre in any medium from someone recommending a book, to even begin to judge if what I'm going to find on the other side of the recommendation is probably going to at least be fairly good. A bare recommendation, no matter how glowing, carries no signal. Let me know what else you think is good, and I can start to get an idea of whether we're in alignment, because otherwise there's a decent chance we very much are not.
