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.
I think that’s kinda the point of allegories - they are timeless and open to interpretation. People read animal farm and can apply it to various parts of society, politics, philosophy. If it was too detailed and specific it would be MORE like a history book and just about the Russian Revolution. Which would likely not have had such a wide reach as it continues to have.
