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.
I don’t even think Wheel of Time is that good apart from the overarching plot and some of the worldbuilding.
Shit I don’t even like how the worldbuilding is done, I just like the world. The way you get it though is really excruciatingly slow.
