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.
Ew, Lolita is so obviously not a love story, tf? I haven’t read it, but I know what it’s about. Sure, the story isn’t given in a clear-to-see way, and it’s from the pov of the perpetrator, but… she’s a child, it’s so obviously not a love story.
