Let me just start out by saying, this movie was completely and perfectley amazing! I was soooo happy that they gave us what we've been waiting for.
I actually enjoyed some of the differences! It still gave us the story we all love, but with a couple of new things added. Like the funny moments in the movie. I didn't think they'd do that, but I loved it! For example, Edward's first reaction to Bella, Bella's friends, and even the Cullens. I love how they made some of those moments funny.
I also liked how they portrayed the Cullens. The scene where Bella goes to the Cullen's house was semi different, but I really enjoyed it. Emmett was so funny! And Rosalie is even more of a *cough*beezy*cough* in the movie. Hahaha.
And one more thing, I LOVED the new ending. I got chills from watching that very last scene. Adding Victoria to the prom scene was completely genious. Period.
So all in all, I think the differences made the movie even better than it already was.
