Fair question. Well, mainly I would need to specify further: do not watch the movie (before reading the book). So maybe first I should apologize for being too succinct. I feel like the movie might spoil the story while the book is so much better. I'm not going to tell people not to enjoy this or that, I consider the movie fairly bad but it's not up to me to choose if someone likes it or not. But then, as an adaptation I feel like the movie does a terrible job of translating the book to a screen, losing the real soul that the book has.

It would also be fair to say that I have only watched the movie once, when it released into theaters years ago, while I've read the book a few times, so my perspective may be skewed if only by just what I remember of the movie instead of what the movie is really. For those like you, who have read the book and want to consider watching the movie, I'd say go ahead, with expectations low enough it might be enjoyable somewhat x)
