There's a bunch of people who saw this movie that will tell you it's crap because it wasn't just like the book. But the changes in storyline, if anything, enhanced the movie.
I was afraid that I'd be bored (because I already read the book and know exactly what happens when), but the plot twists kept the movie from being a play-by-play of the book, and I loved it for that.
There were *so* many great scenes that I will definitely be seeing this one again the first chance I get.
