Animal Farm-- Why I chose it

Recently, I started reading the book Animal Farm by George Orwell. One reason I chose this book is mostly because it's a classic, and I have also heard it is a very good book. I saw this book in a book store as I was there to get Farenheit 451; so I picked it up because it sounded interesting. Apparently, it is supposed to be a book representing why the government shouldn't have too much power. As I have read into it a little, I have seen hints of the government kicking in. So far, the animals have run out their farmer and named their new farm, Animal Farm. They have also established the rulers, which are the pigs because they say they could make the best rulers. What do you guys think, will the pigs turn the new Animal Farm into a complete tyranny?
