I have a somewhat opposite opinion on this or at the very least half-way from it. Some aspects should be described even in great detail if it is {a} integral/unique to the plot, {b} something that doesn't exist in our world, {c} not an item from mass media, or {d} not common in almost ever other story out on the net.
However, countless paragraphs of description or even self-examination is just word vomit.
I suppose it has something to do with my background in Business Administration. But for me, I'm inclined to think say more with less
EDIT: One of the choices was supposed to be negative (posted the other way around).
