I loved the Peter Jackson LOTRs films but we will have to agree to disagree about the extended cut haha ๐ My wife loved it and a lot of people do so I'm probably the odd ball here lol.
Tolkien isn't super descriptive, and this was after Annatar disguise has been discovered
Yes its quite vague but he must have been able to portray himself as good when he wanted to, since he forged the rings with Celebrimbor for thousands of years. Though I do suppose that he could have manipulated him in other ways as well.
I thought Amazon doesn't own the right of Sirmarillion so we won't see the name Annatar being used
You're right. They don't. They only have access to LOTRs and the appendices. The appendices are quite vague though and not much is written on the second age. That gives the show runners a decent amount of leeway to create their stories - which could be a good thing or it could be bad depending on ones perspective. I'm hoping that they don't stray too far from cannon but we will see.
