So, we actually saw "Breaking Dawn, pt. 2" last month, and here I am only just now writing it up. Oh, well. Annalee Newitz wrote a really good movie review over at io9.com (which made pretty much all of the points I had wanted to cover) so you may just want to read that instead.
SPOILER ALERT: Bella gets to be a vampire, FINALLY. It only took four movies' worth of moping and one killer pregnancy. And of course she is the sparkliest of them all.
Also, she has an Uncanny Valley super-baby with a stupid name and a built-in babysitter/bodyguard/boyfriend; how SUPER EFFICIENT and not at all creepy.
Then the evil Volturi get all huffy with the Cullens, and there's a pose-off which the Cullens and their Super-Friends totally win because of course they do.
Things that I liked: hey, Bunk from "The Wire" is in this movie! Just for one scene, but still: WENDELL PIERCE, y'all. Also, Lee Pace gets to wear guyliner and be a Sexy Rock Star Vamp, which I guess is good practice for being a Sexy Rock Star Elf in "The Hobbit" movies.
Things that provoked maximum hilarity: Jacob coming out (as a werewolf!) to Charlie, Bella's dad.
Things that I will miss about the "Twilight" saga: Charlie's moustache. THAT IS ALL.
