Legend
to me it was the non-Tolkien characters - Nori and Lenny Henry, Bronwyn, Arondir, Adar who were the most interesting and there stories most compelling.
The Elrond-Durin Mithril story seemed a little superfluous in the end.
I think Galadriel being both a POV character and very competent from the start may have had her coming across as Mary-sue or DMPC. She was there to drive the high level plot while the other characters had smaller stories where they could just focus on their space.
Galadriels flaws made her interesting but the mystery was tied up on who is Halbrand and where is Sauron rather than ‘whats next from Galadriel’
Galadriel isn't a Mary Sue. Her skills make sense in world, and she's an elf they're just better in world. 5000 year old veteren.
Her skills do make her kinda boring as she can pretty much defeat anything not named Sauron fairly easily (cf cave troll vs troll in movies with Fellowship).
And year the not hobbits, Stranger, Adar etc were more interesting imho.
