Here's my experience of the novel and why I love it so much:
I have read Nineteen Eighty-Four many times in English and excerpts in Persian (I have yet to find a decent/complete pdf of the book). What is interesting is that if you replace certain names, places, dates and so on with Persian names, you essentially have the history of the Islamic Republic of Iran, the history of the past 32 years of fascism and dictatorship. Obviously I know only these two languages, but I'm certain that if I read the book in Korean or Russian (to use examples of other languages and countries steeped in authoritarianism), I'd get a similar result.
What I'm trying to say is that Nineteen Eighty Four is not only a flawless piece of literature, but it is also remarkably accurate. Orwell truly understands revolution, counter-revolution, dictatorship, cult of personality and human feeling. Perhaps you need to have experienced dictatorship and totalitarianism before you understand just how scarily accurate the book is.
Emmanuel Goldstein's "Book" is a very good account of just exactly how dictatorial regimes acquire and consolidate power. Oligarchical collectivism, war is peace and so on are not fiction, they do actually exist. Orwell's understanding and depth of perception (no doubt due to his own experiences as an anti-Stalinist democratic socialist, and fighter in the anti-fascist International Brigades) of a stolen revolution and a totalitarian regime are very accurate. His portrayals of the "proles" and the way they are manipulated by Ingsoc and The Party into never awakening and revolting is again something which goes on day to day in the real world. Perhaps you need to be of a certain political inclination to appreciate Nineteen Eighty Four. I don't know.
Political stuff aside, the character of Winston Smith as an everyman fighting the system is something I feel a lot of people could identify with, as are his attempts to stay free and enjoy simple pleasures (e.g. a love affair with Julia) that we take for granted in the free world. The scenes with O Brien and O Brien's lucid, yet disturbing, explanation of the aims of The Party are nothing short of awesome.
Ultimately you can't force yourself to like a book, but Nineteen Eighty Four is truly magnificent.
