I'm cautious.
It's easy to be concerned with the wildly varying quality of shows today. The Witcher kind of has me woried for shows like this.
But it's also hard to judge the quality of a show by just a few photograph. Post-processing and seeing things in motion will make it look quite different.

She does have a beard though, I think.. looks like chops.

Galadriel: starts speaking in a deep echoey voice

Sauron: Understandable, have a nice day

Yea, like I said, I don't know much of anything about her character outside of the movie timeline. She's just such an ethereal character, that has always struck me as kind of this cunning chessmaster type, setting the scene for events to unfold as they should. Seeing her in full armor, wielding a sword, to me, would be akin to seeing Wesley Snipes' Blade walking around in a business suit. Just doesn't compute lol.

Looks a bit too much like The Witcher. I will still watch it, but with expectations low.

Galadriel being a battlemage is exactly what I would expect her to be when she was young running around kicking ass and taking names. Its pretty much how Tolkien created his magic based characters. They only use magic against magic but the majority of the time, they are taking heads with mundane weapons just like Gandolf.

It's because the pictures are hyper HD, it looks like a Christmas catalogue :D

Anyway, by the descriptions, it seems that the story is going to take place at the middle of the Second Age, around the time when Sauron is Annatar. So the battle for Eregion and the closing of Moria (Khazad-Dum).

I could be wrong, but we'll see.

I'm really looking forward to this show. I was really excited about the Witcher and the wheel of time and was kind of disappointing so I hope this one delivers. I need a new good fantasy show to dive in. 

Around the fall of Numenor would be about 1500 years later.

What I'm thinking is this story will take place surrounding the forging of the rings of power. They could do a time jump at some point since many of the characters are immortal.

Elrond would have had his romantic arc with Celebrian around the time of the sack of Eregion. Also, Galadriel would have been militarily involved around this time too. Numenor comes in at the end to save the day.

Another option is to go the anthology route.

I'd love to see Silmarillion retold at some point. Most of the main events take place in the last 150 years of the first age starting with the Battle of the Sudden Flame. But part of the story would have to take place with the fleeing of Aredhel from Gondolin, because Maeglin factors into the main story - and that's before the Battle of the Sudden Flame. Although, Feanor's story, Ungoliant, and Morgoth would make for an interesting episode. They'd definitely have to reshape the main story, making one of the Elves that survives the age a main character - probably Maglor or Maedhros, Galadriel would be a potential since she's "off screen" most of the time in the books, but present for a lot of the events. What shows have been doing now to fairly big success is having multiple starting points in a timeline, so they can tell different parts of the story from different parts of the history while weaving the story. It wouldn't be an easy adaptation, but with enough planning, it's doable. And I want to see it!

I'm definitely intrigued by the show. Most of the complaints about it so far feel very shallow and generally just come off as knee-jerk reactions to superficial aspects of the show. I would say I'm cautiously optimistic right now.
