I would have to say that BDpt2 is my favorite movie in the series. While many people didnt like the ending, i LOVED it.
It added just a little something and gave us a new idea about alice and aro. In the books its only in bella's POV so we never get to see any of that. And i loved how they just tied it all together at the end with the credits and the flipping pages that tied it back to the book.
I really felt that each movie got better and better. When my mom and i watched all of the other movies before we watched PT2, that was really evident. I remember watching twilight and were both like ," you know it really was the fans that kept it going. compared to the books, this is BAD." And thats true, without the fandoms, twilight would have never made it past that film festival back in '08. (seems weird that only 4 years later, its over
As for the books BD is also my favorite, You got to see bella evolve from a weak human to a magnificent vampire. ITs what the entire saga is leading up to. I also definately love the introduction of renesmee.
Over all BD was my favorite in both. I loved the movie and the book and couldnt have asked much more out of the movie. I deffinately couldnt have done better myself.
