I don't need to see any icky love stuff. (I very much prefer not to on the whole, imagination being so much more satisfactory than almost anything I've ever seen in print.) What I would have liked though, is to have been able to see Marianne and Brandon interacting, so that I get a sense of the energy between them.

An example of what I mean is the amusing mini-scene between Elinor and Edward near the end of Ch.49, which starts with Edward's little rant ("A letter of proper submission!....).

 "You may certainly ask to be forgiven," said Elinor, "because you have offended; -- and I should think you might now venture so far as to profess some concern for having ever formed the engagement which drew on you your mothers anger."
  
He agreed that he might.

"And when she has forgiven you, perhaps a little humility may be convenient while acknowledging a second engagement, almost as imprudent in her eyes, as the first."

This scene is amusing in itself but I think also works on another level.
We have learned through the course of the novel that both Edward and Elinor have a sense of humour. Edward's is only seen in occasional flashes, but because we 'see' Elinor's thoughts we know that she often responds to difficult or annoying circumstances with irony and/or amusenent. The scene which I've quoted gives me a vivid sense of their relationship. It taps into our prior knowledge of the characters, and shows how this commonality in the turn of their minds works when they are together. It shows the synergy between them, which reassures me that they fit together very well.
