The only real fault in the movie vs. the book was the fact that Alice can't see the wolves or Renesmee, but in the movie, she can. Even though they switched that up, it was still BY FAR the best movie of the saga. Better than all of the others put together, and tripled. In the final scenes it felt like Stephanie Meyer had ripped my heart out, stomped on it, tore it to pieces, then gingerly put it back together and gave it back.
