Anyone who hasn't done so yet should read 1984 from cover to cover.
It's not a very long book, it's easy to read and it's got tits and violence too.
At first some things might seem unlikely and it seems like things only work because that's what the book is about. For example:
There is a scene where a political speech is held and during the speech the enemy of the nation becomes its ally and its ally becomes the enemy. The speaker is informed and he continues without a pause but now he is talking about a different political constellation. He is telling the people the same thing as before, but with switched enemies and allies. The people notice this of course (they are not dumb) and they see all the flags that were there to decorate the place and that are now wrong. They immediately assume that there must have been spies who changed the flags, because their new ally had always been their ally, and their enemy had always been their enemy.
Another example is that the people in 1984 don't seem to get the opposition of the main political mottos:
Freedom is Slavery, Ignorence is Strength, War is Peace
The scenes seem totally forced and unrealistic when you are just starting out with the book (who could be so dumb and fall for it, right?), but please, stick to it. Read on. Once you made it to the end it will become clear that this isn't nearly as impossible as it sounds and the people don't just "fall for it" because they are stupid.
The book will change you.
