"Not every writer was writing in such convoluted way."
Sure there were. But unless they're Mark Twain or Ambrose Bierce, they're probably not much worth reading.
Before screens, people must have gotten far more enjoyment from authors painting mental pictures in tiny detail.
We have HD video as an option now. A long description of a rose bush doesn't do it for me unless it's needed for the actual narrative.
I strongly disagree. Being convoluted does not make the text more worth reading. It makes it more fun for one kind of reader. That is about it.
Being well written and pleasant to read does not make the text, whether fiction or real like account less worthy.
