One thing I think people underestimate is how much rigging, one star review bombing, paid reviews, and so on flood Goodreads. Less common in contemporary literary fiction than other genres but this kind of thing below is happens a lot. Also a lot of power GR reviewers have very commercial or genre-specific tastes yet read many free galleys through Netgalley that are outside their tastes. Tons of “DNF, I got the galley from Netgalley and it’s in 3rd person POV! I hate third person!” and “DNF because these are short stories and I hate short stories” type reviews on there.
