My issue with the Galadriel characterization isn't her morality per se, it's how blunt and crude she is in diplomacy yet she is the COMMANDER of the Northern Armies (whatever those are). If I had any respect for the writers I'd think they were trying for a Patton or MacArthur type of personality but....wow.
Anyhoo, some nitpicks.
A. Galadriel can see land an HOUR before humans. I'm gonna go with "she can see the land in the pre-dawn" rather than "Middle-Earth is flat and she can just see FARTHER" (though IIRC in the very early days M-E WAS flat)
B. The Armor. Hoo boy. Numenor scaled armor is, I think, supposed to represent some sort of advanced material signifying their technological and cultural accomplishments. Ceramic or some sort of dragon scale perhaps? Something a NAVAL power would develop that wouldn't send their soldiers into the deeps if they go overboard?
C. But where did Halbrand get his dope copper/aged bronze version? Make it himself? Heck, where did Galadriel get her exquisitely fitted high renaissance full plate? Did they make that on demand as well? I can only presume they did.
Those two "hero" armors were actually pretty cool, especially the very fine mail over her joints (woven cloth or actual rings?) But the numenorean stuff was far too monotone and indeterminate in material with that elaborate neck collar and the armor patterned shirt they wore under it.
D. the tactics....so lemme get this right. We give up a SUPREMELY fortified outpost, with a single narrow entrance, for 3 low houses in a field? This seemed like the problem with having the tower but ALSO needing a cavalry charge. Solution...walk to a field!
I can get that the first group of orcs they fight might be just a reinforced scouting party because Arda had his forces spread out looking for the humies, he was in disbelief that they walked an hour away and gave up an ENTIRE day of movement to instead reinforce the village.
E. the whole flood thing. Sooooo, this was an ancient First Age Sauron construction? Some last ditch defensive measure if invaded? Having a magical key instead of a keystone you knock away probably makes more sense if your army is composed of chaotic rabble like orcs and dirty southrons but seems like a bit of physical effort would have accomplished the same thing AND Arda could have just relocated HIS humans (if he really wants to lay claim to Mordor) rather than kill his new workforce.
I'm starting to view this show as "alt-Tolkien" pastiche, kinda like Dennis McKiernan's Mithgar books (which are FANTASTIC, BTW, just not at the level of Tolkien) and it boosts my enjoyment a bit by taking off some of the weight of expectations.
BTW, loved the ENORMOUS hilt of Adars sword. I dopn't think he ever uses it, but he has a zweihander hilt on what must be a longsword at best.
