Like, the whole "master smith discovers alloys" thing was a way to show the three elven rings being made of the different metals without directly referencing the Silmarillion describing them. When they pour out the "alloy" to make the rings they're clearly made of different metals.
But like, who was that for?
Real huge lore nerds you just pissed off because Sauron wasn't supposed to know about their existence or take part in their making? Him not knowing is why his plan didn't work!
But the thing is, Rings of Power is incredibly fun, because it completely ignores source, steals just enough character names & places to get Lord of the Rings fans excited, but it's not boring. Lord of the Rings is about thousands of pages of walking.
Galadriel is a WOMAN and therefore according to Professor Tolkien is useless. Show makes her the one badass in Middle Earth.
I did hate the not-yet-Hobbits, that was not a good invention.
