Read Animal Farm for Eng Lit 'O' Level and, whilst causing the downfall of tyranny seems both an obvious and honourable act I particularly liked the way it tricked me into believing that collectivism was a "good thing" - and also "logical" - before dashing all hopes by proving that no "revolutionary" can be trusted to not turn into a self-serving trough-snuffler.
Decades before his latterday namesake, he understood that regime-change is all very well and desirable but basic human failings mean that you dispose of a Tsar and their replacement soon becomes another; "more equal than others", as he put it.
I can no longer recall if I saw the animation before or after reading the book, nor whether it increased my understanding that it was allegory of actual history because I didn't learn the deeper details of that until later. As entertainments go, it is satisfying to see a work which can function as a children's cartoon on one level and as polemic, for the adults, simultaneously.
