If I parse out what I know about the Tolkien universe from the show and wanting to see that in play, this episode was boring. Also, Meteor man - if not Sauron - who cares? If Sauron, then watching him be mentally deficient, be nice then eventually become bad - what a yawn.
Also all the triumphal and ethereal music score is grating. Oh, some pretty scenery, big city - cue the music.
I got a hint for Numenor - let's have a scientific revolution and move out of thousands of years of middle ages tech. Build some airplanes and steam ships.
Last, Galadriel is an unpleasant person and greater forces arrange meetings with kings at sea. Oh, how the great beyond has to screw around with artifacts, portents and mysterious manipulations.
Yep, I get the problem of theodicy - you have omnipotents floating around who let millions die a horrible death until the great heroes or some unknown commoner finds the magic tea pot and saves all. Yawn.
