with the exception of a few specific scenes, like the reveal of Eregion in the first episode... and the slow motion shots showing the fallout of the war of wrath... i wasn't really impressed with the visuals. especially the design decisions for pretty much everything. the stuff at khazad dum is fine but the dwarf armor is silly (beard armor means they can't turn their necks at all).
i just found myself thinking, you did JUST enough research to look at armor, but not enough to understand how pieces fit together. and pj's stuff, each culture had design decisions that made sense. horses were extremely important to the people of rohan and you can see that in their armor, their clothing, their decorations. and it is NEVER explained, but you see it and it makes sense. same with gondor, same with any of the elves.
galadriel's plate armor looks right from a glance, but on closer inspection it's basically not functional at all, with random bits of bunched up chainmail in the joins which means limited flexibility at best, getting yourself killed at worst. numenorian armor has scale mail, but... only sort of. and why? they are like pseudo roman but don't use roman armor... okay, fine... they have horses on their sword pummels but they live on an island and don't have any other horse iconography... i just can't find any through line in their stuff, none of it actually makes any sense.
