The length of a school year
A novel can linger on lessons, detentions, and the slow suspicion that something is wrong. A year feels like a year because ordinary weeks are allowed on the page.
On the screen
The length of a school year
A feature compresses a year into an evening. The plot beads remain. The weeks between them often vanish, so the castle can feel like a series of set pieces.
Neither pace is a mistake. They are different instruments. Missing a side plot on screen is often a runtime choice, not a denial that the chapter exists.
