To start off, some were drastically impressed by the film and basically HAD to get the book. Others might not have been that impressed, maybe vampires weren't on their "good" list. I, on the other hand, was both impressed and, well, not impressed. Most of it was exactly how I expected (wonderful!) and the other parts were... different. As I have read the book, it's natural for me to notice every part that was different from the book (I read Twilight 5 times). I also realize that because the book is so large, it wasn't possible for them to make a perfect movie without it going over 2 hours. But overall, it was almost everything I expected and wanted it to be. Twilight is an AMAZING movie!!!
