This is the one where nothing really happens, except there's some evil lady in the snow, but the characters only vaguely care about her because of their love triangle.
This is my favourite Twilight movie, though, because of Jasper's accent. Jasper looks like an awkward, uncomfortable Harpo Marx. In the first two movies he doesn't speak much, but when he does it's with a neutral North American accent. Then, all the sudden, in this movie, he has a thick Foghorn Leghorn accent and spends the next three films screaming things like, "AH DO DECLARE". It is hilarious beyond words. In my heart, Jasper's accents are truly the stars of this franchise.
