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 kinda liked Dan Brown’s books. Mostly when I was mentally tired and wanted a book that I could pretty much finish in an evening. Also because they often trigger been-there seen-that moments when culturally relevant sites are mentioned.
Yeah, they’re basically pulp on more expensive paper.
