This was a great and very entertaining movie! Not only was it filled with awesome music (as expected) but the whole movie had a slew great cast and characters that made everything even more interesting!
As many people have stated the books and movies always vary from each other. Take the Harry Potter series for example: if you hadn't read the books previously and went to see the movie you'll find that you're aware you're missing something. I've read all the books and found that this movie was great for those already introduced to the Twilight series, but a little confusing and fast for those who weren't. The casting was great, I was amazed by the Cullens personally. However, I was disappointed by the relationship between Edward and Bella because it seemed more like a lust and a fight than it did a gradual unknowing love story. But I did leave the theater very happy with the movie overall and plan on seeing it again.
