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 feel like thinking your ‘rating’ of The Bible (not you personally, but the hypothetical 5 star rating date) makes any difference is a red flag of it’s own.
Unless they are rating the quality of the binding, printing, etc of a particular edition.
