As someone who loves Goodreads, I've largely ignored the "bad parts" such as what this article is describing.

I've seen these review bombs on plenty of titles once certain authors or books become heavily politicized. Sometimes decades after the fact of their published book.

You also see a general sentiment of people who want to voice their opinion on how bad books are to the point where they say "DNF" and thus leave a scathing review over a single chapter.

I don't know if there is a fix to this problem, but I do wish more people read the entire book instead of judging it by its metaphorical cover.
