Exactly this, cheah. The novels of my beloved 60s and 70s horror paperback era are slim little 150-200 word things. You can sit down and complete one in an evening, or spread it out over a week of dips and dabs. The 300, 400, 500+ page behemoths of today are the children of Stephen King and those chasing after him. For Fantasy, replace Stephen King with J.R.R. Tolkien and the illusion of length being equal to prestige.
