I see this happening a lot now where people are saying if it does not progress the story/plot or flesh out the characters then cut it. I believe this came from someone seeing this advice about writing a movie script and applying it to all fiction writing. Movies are a very different medium than novels. Movies take about 2 hours or less of your time and are meant to watch in a single setting. A novel takes you into another world and maybe as another person. You read a book over multiple sittings (usually). Sure, plenty could have been cut from American Psycho, Harry Potter, Lord of the Rings, and etc, but we like being in this world and seeing all the adventures the characters get into, or hell, even some of the things in some class in Hogwartz are fun just to read. Not every page has to be dedicated towards forwarding a plot or fleshing out a character. Sometimes we just enjoy characters. Sometimes we enjoy just reading about what characters do in many situations. I think this cut everything is just misunderstood advice...and in novels it could be all the wrong advices (thanks arnold).
