“My preference was three seasons, but I also wanted to allow the storytelling room … Three books, three seasons. It feels right to me.” (townandcountrymag.com)

This oversized final season gives space for nuance, expanded character arcs, and emotional closure.

Behind the Scenes: Filming Amid Industry Turmoil

Originally slated for 2024, production was delayed by the WGA and SAG-AFTRA strikes. Filming eventually began in May 2024, enabling the backlog of post-production work that delayed the movie counterpart’s filming (en.wikipedia.org).

Jenny Han is directing the upcoming film adaptation herself, though as of December 2025, only the script is completed—filming hasn’t started yet (cosmopolitan.com).

Why Season 3 Matters: The Power of Ending Strong

Adapting each book into one season was deliberate: to conclude the trilogy faithfully, rather than risk overstaying its welcome (ew.com). Jenny Han’s creative stewardship ensures that emotional arcs—from first love to heartbreak, reconciliation to maturity—get full expression.

This strategic wrap-up enhances credibility and narrative integrity, showing a brand sticking its emotional landing rather than diluting the story for longevity’s sake.
