“Filler” is very subjective. A very long chapter going on a tangential introspective mourning thoughts may be viewed by some, as it “doesn’t move the plot forward”, but it can be the most pungent point of emotional connection in the entire novel for others. Sometimes going on talking about minor characters routine is kind of the main point of an author’s intention, but it may read as “filler” by some. Or something like Brandon Sanderson books, where his fans enjoy spending more time in that universe, but make their novels very long.
