If you've read the book before seeing the movie, you will appreciate the story more. All my friends who saw the movie without reading the books enjoyed it a lot, but also interpreted Edward in a very different way than those who read the book first. As with any movie based on a book, there were lots of parts that I wish were included in the movie, or done more accurately, but this is the closest to the book any movie like it has ever come, in my opinion. The special effects also left something to be desired.
