My favorite part was probably room 101 because you got to learn all about the Party when O'Brien explains it all.
I had a lot of hope for Winston and Julia though I knew they couldn't stand a chance against the Party. I actually predicted Winston to die but he becomes a sheep and brainwashed. It was crazy how he thought after he was released from the Ministry of Love. Caring about a bogus war and loving big brother.
This book does raise a good point of remembering to be a free thinker and don't become brainwashed about the media. To check stuff out and don't believe everything you see on the news.
