For what it's worth, the Tolkein Estate is involved with the production, because they were unhappy with Jackson's adaptation.

The source material is a vague outline that stretches out over centuries.

But I'm tired of purists looking to complain about film and TV adaptations, because there are necessary constraints:

- You want story arcs that fit within a season.

- The timeline is compressed to keep the story moving.

If you don't do this, people will get bored of the show. And in the end, you care about people watching the show, not satisfying purists.
