This book left me feeling slightly haunted and paranoid, which I believe the writer intended. Although I don't think we find ourselves in the same society today as the one portrayed in the book, I definitely see similarities. At the first mention of the 'victory cigarettes' (or coffee) I thought of 'victory fries', or 'freedom fries;' I forget which one really happened ;)
Ironically, while finishing the book I read about the rewrite of Mark Twain's 'Adventures of Huckleberry Finn' and 'Tom Sawyer' to exclude a certain word and replace it by another (not quite the same). Hello, Newspeak!
At times I thought the book went on a bit (specifically the parts where they read from The Book) and I had to struggle to get through it; nothing I hold against the book though, it seemed to fit the story.
The rebellions of Winston and Julia seemed small when held against today's society, however, they already lived in theirs for a long time and didn't know any better. Although I hoped for another ending, the way the book ended added to the haunting feeling I had.
It all does not seem very unlikely to happen.
