My biggest complaint was how thin the allegory was. Like, Orwell didn’t have to use animal farms at all, it read like a history lesson for most parts. I felt between chapter 3 to chapter 8 were mostly just boring and pigs Doing a power capture slowly. Did chapter 3 to 8 help create the impact of chapter 9 and 10? Absolutely. Could they have been done better? I think so, it didn’t have to be read like a history lesson.
Not trying to be bellicose at all but, to my taste, Orwell’s best fiction is in his early books. And I find “Animal Farm” and “1884” rather unsophisticated when compared to other dystopian novels like “We” or “Brave New World”.
