How does the book end? What is your reaction to the end?

The pigs continue the longstanding pattern of awarding themselves more and more privileges. They buy a telephone and subscribe to magazines. They even wear Jones’s clothing. One night, Napoleon holds a conciliatory banquet for the farmers. Pilkington makes a speech in which he says he wants to emulate Animal Farm’s long work hours and low rations. Napoleon announces that the farm will be called “Manor Farm” again, the animals will call each other “Comrade” no longer, and they no longer will march ceremoniously past Old Major’s skull (a practice he denies understanding). He also declares that the farm’s flag will be plain green, devoid of the symbols of the Rebellion. As the animals peer through the windows to watch the humans and pigs play poker, they cannot distinguish between them. Animal farm plays out like Stalinist Russia and countless other "utopias" that promised a glorious equality. People, in this case pigs, eventually take advantage of the system using rhetoric and violence to further their own ends.
