I just finished 1984. Its effect on me was most unexpected and profound. But I can't articulate just what that effect was, yet. It was, what might be called in Newspeak, doubleplus ungood by Party standards. If you plan on reading it eventually; read no further.
The story was so sad. More than sad, tragic. Not because Winston and Julia never get to be together, but because they no longer want to be together. Not because they are not allowed to believe in truth, but because they no longer care what truth is. They were alone in the world, the they found each other and knew what it meant to have kinship, but they betrayed each other for an empty existence.
There is only one victory - your mind. If it is conquered - you have lost. But if you keep it - you win.
