I think at the point where you want a more nuanced review of a book you'll have to do some reading and adding more stars won't make it any more clear. People usually write why they gave a particular rating anyway. Having more stars doesn't make them have to write any less. 37.5 Stars "Ah he finds Hemingway's lack of first hand experience in war blatant compared to Orwell's and thus not as good at writing a story about it, I see clearly now with the right amount of stars."
