Lord of the Rings Series -- Amazon

Again, they only can do 8 episodes a season and only use the trilogy and appendices
They trying to find an efficient way of synthesizing 2 epochs into a tight(ish) narrative
I’m sure the concerns y’all are expressing were discussed AT LENGTH in the writers room - and what we are seeing is the compromise of many strong and heartfelt conversations/fights
And it’s not canon - it’s an adaptation of canon

Right, so tell a story within those confines. It's totally doable, there's a lot of depth written in the LotR that you can pull from to tell a story within this time frame. They are setting up the fall of Numenor and the forging of the Rings of Power. It's a pretty awesome story. There's a lot of wiggle room in that. You've paid for the IP, so use the IP.
