It is quite frankly baffling how they managed to be wrong about this. They knew this guy fell from the sky, from the realm of the Maiar, while Sauron was already well established to be on Middle-Earth for centuries... how do you make such a mistake? Then they treated the big guy in ways that would most certainly make a Sauron kill them all if it was him.
Also, who or what even were the Feminems? They can't be Ringwraiths because duh, no rings, but their spiritual bodies surely looked like wraith.
It feels as if they were just put in there to give the series some Ringwraith like enemies, just as the writers didn't feel they could work a series without Hobbits... it is fascinating how little faith they had in the plots set down about the Second Age by Tolkien.
They shoved halve of LOTR into it with Wizards, Wraiths and Hobbits because they could not fill a series without those.
But he did. If he wanted to win, then all he needed to do was kill Galadriel while she was in his Mind Control. Hide the body and voila, Celebrimbor would have crafted the 2 Rings just a Sauron wanted. The only reason there are rings at all now is Galadriels hybris, believing that she can outsmart the guy by making 3 rings instead of 2, not to mention that she hid the fact that Halbrand was Sauron, which would have made Celebrimbor and Elrond most certainly stop the ringmaking at least until they could be sure that Sauron had not tampered with the materials and crafting process.
That is all basically just Sauron being veeeery lucky. Galadriel could probably not have helped him more if she had accepted his deal.
I hope so, but from all their reactions to critics and what they already wrote about season 2, I have huge doubts. They do not seem to be able to deal with critical voices or see their own faults. Probably a result of that atmophere of (self-) congratulation that is very strong in Hollywood. "You are great, you write great, everything is great, fuck the critics."
Hopefully Amazon tells them to shut up and get Peter Jackson to help them. They sorely need it.
