Well, then studios should take more effort on doing it. Hollywood is not poor after all. If Amazon is willing to pour over 1 billion dollars for a Second Age Fanfiction, why won’t Warner or HBO are willing to pour billion of dollars to make a live action Silmarillion? The costs prove to be worth it when they do that in LOTR trilogy or Avatar. So I’m definitely very into the live action.
Moreover, they can still make a cohesive narrative for the Silmarillion, all the timelines and years of events are stated in the History of Middle Earth. Tolkien even left tons of notes and drafts which could be imaginative spaces for showrunners.
