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.
It’s actually a book I use when I’m learning a new language, I read the translated version in x language. Why? Because it’s such a quick read and it’s so simple, not because it’s good. I’ve read it across languages and years of my life and yet I still don’t get why it’s targeted at adults either
Oh my, this is a genius idea! Thanks.
