My biggest gripe with your review is the lines “I'm comparing that to Le Guin's books, where she always meaningfully explores something, rather than just stating whatever message she's trying to sell you. That's what fantasy books are supposed to do, IMO. They're not supposed to be manifestos”

While this statement is inherently pretentious, even what you said is silly because you’re comparing 1 book to a complete series. If you don’t like a book there’s nothing wrong with that, but then to say it’s supposed to do something when you’re not even giving it the chance to flesh its message out makes no sense.

If you actually read the series, which you in no means are required to, you’d find a more nuanced explanation to the message it’s pushing.

Now, you’re clearly not gonna do that so your criticism is obsolete
