The movie itself was great, but the movie did not show just how difficult the "chase" of james/bella was on everyone, how difficult it was for bella to get away from alice/jasper. The movie did not show the extreme bond bell/edward had even in the book. I came up with a way to explain to my co-works(who just started to read the books, or others just wanting to watch the movie) why they need to read Twilight first. The book/movie of Twilight reminds me of Biology class, your teacher has you read a chapter in the textbook then shows you a movie of the same material, but to completely understand the movie you need to have read the book. Twilight is like that, to completely enjoy, connect, and understand you MUST read the book!
