Season One
Episode 1
Real ancient and medieval battles did not look like this. There should be more or less even lines, fighting back and forth, instead of a swarming mass of random troops, shoving each other around.
Galadriel says that Finrod was found by Sauron, and this was the cause of his death. The implication, I think, is that Finrod did not die in battle, but was killed by something with claws. Which could be a werewolf, as in the books.
Episode 2
[Finrod and other Elves are shown fighting Orcs. They appear to be surrounded. Finrod is shoved backwards by an Orc.]
[Shot of Finrod lying in a tomb. Scratches are visible on his left arm.]
[Stranger appears disturbed and speaks emphatically.]
Stranger: Mana. Mana. [Repeated.] ÚrÑ‘. [Repeats both words several times.]
Mana is Quenya for "who" or "what". ÚrÑ‘ is similar to some Quenya words meaning "evil" and "burning". (No, I didn't know this off the top of my head. I had to check elfdict.)
[Several carved trees are shown up close. One of them shows an Elven lady besides a large dog.]
This is almost certainly Lúthien and Huan. Great to see.
Episode 3
Elendil: He's still alive. I suppose he spends all his days in the tower now.
Not only is Tar-Palantir in the show, the tower of Tar-Minastir is too! That's a very interesting detail.
[Wide shots of massive statues, a huge stone city, a grand harbor, and a Minas Tirith-esq palace.]
Amazon's Númenóreans are clearly immensely skilled architects. In fact, the shots of Númenor are my favorite part of the show thus far, and one of the few things I think are incredible works of adaptation.
Episode 4
[Miriel sees in the palantír a huge flood sweeping over the Númenórean landscape.]
We've finally gotten a taste of the Fall.
Episode 5
[A main plotline is that the Elves need mithril to survive, or "their light will fade".]
This makes no sense.
[Galadriel spars with the trainees, first with Valandil only, then with all of them at once.]
Even with blunts, this would be dangerous, but there is historical precedent for it.
However, the choreography is not great, and the duel-wielding and grappling are downright bad. Halbrand's flipping the sword up into his hand is cool, though.
Episode 6
[Isildur shares a few bites of an apple with his horse before going above deck and throwing the apple.]
Isildur throws with his left hand. In the original films, Isildur was also left-handed, which shows the attention to detail.
