Yeah, the battle was really done and I was actually shocked and but saddened when Carlisile died during that battle, felt for Alice when she avenged Jasper it was very well done battle scene and I thought the ending worked very well. And it did "mean" something as it was more proof to Aro and Volturi that they're were pursuing a lost cause in going after Renessme and the Cullens. It would only ending in Aro's "death" along with the "death" of many other of the Volturi.
I do think Michael Sheen's acting, tongue flicking and so-forth was vastly over the top. I don't know why he's being so lauded by reviews between this movie and his small roles in the other ones. Hell I'll take Kristen Stewart's bland, "Ummmm.... Line?" acting over Michael Sheen's scenery gluttony any day.
