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.
The way I see it, RPO is a 5/5 book for people who don’t typically read. It’s an easy read, the story is relatively harmless, and the excessive pop culture references make the reader feel like they’re “in”. I can understand why someone who rank it highly.
That said, it’s awful.
