In the past week or two I've responded to several threads about whether certain scenes are necessary or should be cut, and of course there's no way for anyone to really answer those questions without having read the book, but in my answers I've discovered something that I think I already knew subconsciously but had never really realized consciously. That is: Scenes should do more than one thing. Just characterization, just setting, just plot - that's not enough. A scene, to be effective, should contribute to at least two of those things, and preferably all three. Has anyone else had any realizations about writing lately? Or does anyone want to disagree with or add to my realization?
