I’ve been fairly forgiving of the Peter Jackson LotR movies, and they’re nice shiny fantasy eye candy, even if they lack in substance. But seriously? Introducing a random female elf character in the Hobbit screams awful bad idea.
All of the parts with Liv Tyler’s fish-faced Arwen were the most tedious and groan inducing moments in the original trilogy. But at least her character was semi-canonical (it’s been ages since I read the books, but I vaguely remember at the end of RotK, some elf lady kind of showed up out of nowhere and Aragorn is all “By the way, she’s with me, read the appendix if you care.”)
Also, I find it amusing the spin they put on her being a “lower” elf . To really get what that means, you kind of need to be familiar with a lot of First Age stuff and inter-elven racism. Basically, most of the elves in Middle Earth are “Dark Elves”. There is a huge flowchart out there on a site somewhere or another that gives all of the details, but basically, there are 2 kinds of elves. The light elves, who went to Valinor, and the dark elves who didn’t. Of the Dark elves, there were the Grey Elves who started off toward Valinor but for some reason or other didn’t make it, and then there were the really Dark Elves who said “Walk across two continents AND sail over an ocean? No thanks!” (these should not be confused with the one guy who is specifically referred to as a “dark elf”).
So, um… she’s a “low” elf kind of the way that tribes of Israel who didn’t cross the River Jordan to settle are “low” Jews. It’s a bad explanation that doesn’t really give the appropriate context to idea they’re trying to convey.
