I’ll go with the low-hanging fruit: Mein Kampf. I’ve read it, cover to cover. As a piece of propaganda, it’s good. As an example of good writing? Absolutely not (though I will admit I have only read it in translation). Oh, and the whole fascist, racist, and generally shitty worldview of the author that he infuses into the text. And the fact that the author is literally Hitler. You 5-star that book? You’re a Nazi. Period. And as a Jewish person, I don’t look too kindly on them.
Ready player one was my favorite book for like a year. I’m a 2000s kid so I have no nostalgia/understanding of 80s nerd culture, so it was a fun window into that stuff. It was also the first techno dystopian(ish) book i had read.
Then I read stuff like Neuromancer and actually got into gaming. Also, his other book(Armada ig) is a blatant enders game ripoff without any of the stuff that makes EG awesome.
It’s also a ripoff of The Last Starfighter, which I think is even mentioned at the beginning of Armada, but it’s still a ripoff. Ender’s Game kind of came first (the story came out, then The Last Starfighter, then the full Ender’s Game novel). Armada manages to rip both off, though, and isn’t a quarter as good as either.
