hmm this is hard cos i love the movie as a whole and most of the scenes are memorable. But I like EB breakup scene (Kristen totally portrays Bella's disbelief and angst here), most of Bella's scenes with Jacob (maybe because Taylor is such a great Jacob and Kristen seems so natural interacting with him), the Meadow scene with Laurent (again, just as i imagined it in the book), the scenes in Swan's house with Alice and Jacob, the ending scene when Edward and Jacob nearly fights and Edward proposes to Bella (Rob is dazzling as Edward). But my utmost favorite scene gotta be the cliff-diving scene when Bella actually smiles when Edward tells her not to jump, then tells him that it's because he won't stay with her any other way. Kristen REALLY personalizes Bella in this scene and I'm happy
ETA: oh yeah also love Jasper and Emmet's scenes/lines. Glad they found a way to sneak in the information on Jasper's ability somewhere.
