Of the Twilight movies, Breaking Dawn part 1 is definitely the best. There were a few places that managed to be unintentionally hilarious (or painful) though because the directors didn't trust that their visuals were strong enough, even though they definitely were.
As for Breaking Dawn... definitely best one out of all of them. The Twilight saga is one of my guilty pleasures. There are moments when I had to put the books down there was so much teenage angst and Bella being over-dramatic but I got through them. I think the movies have gotten increasingly better. Both R. Patz and Kristen have had more roles since starting twilight and have grown as actors and I think it is visible in this movie. One of my best friends and I saw it Friday and we both agreed it was handled the best. I think the kissing scenes held on way to long; instead of giving just enough, there was a little too much. Otherwise, everything was spot on in reference to the book. Hope you enjoy seeing it!
