Two major themes in the book are as follows:
Sadly, the story was edited near the end to produce a more pro-west/anti-communisim message by the CIA who funded the movie. It was made during the Cold War to present Orwell's ideas in a more 'Good guys win' fashion.
I give this book 5 out of 5 stars. It brings people to question their government and never idly stand by. This instills the little voice in our heads that questions when everything is perfect. It brings the words "but some are more equal than others" when we here about equality. It takes a person away from ignorace and toward curiosity.
