I was impressed with how well of the a job the fx team did with Renesmee as a baby and her aging. The changes from the book were awesome and overall the disappointments I have is the length of the movie, it should have been longer especially it being the last of the Twilights. Number two is there should've been more to the story of Bella finally becoming the Vampire she was born to be which was a very important point. There could've been so much to see of her interacting in the Cullen Clan and sharpening her powers and hunting skills. The story rushed into the confrontation with the Volturi and missed out on all the rest of the story of Bella becoming a Vampire!
Pros great story, great actors, great fx's, they all lived
Cons too short a story of bella as a vampire, should've been longer for the farewell
