Least Favorite Characters in Tolkien's Writings

[Curufin]

I've seen plenty of threads where we talk about 'favorite' characters - this is kind of the obverse of that.

What are your least favorite characters in the works you've read of Tolkien's, and why? And they don't have to be 'evil' or 'bad' characters.

Don't forget the 'why' - that's the interesting part.

Me:

Lord of the Rings:
Frodo. I've never liked him. Sure, he has a heavy burden and all that, yadda yadda, but it's Sam that does all the hard work and gets none of the reward or renown. Frodo doesn't have much of a personality, and he can't even complete his task at the end. Curufin is not impressed.

The Hobbit:
I've only read this book once, granted, but Thranduil is a big jerk.

The Silmarillion:
Túrin. Probably my least favorite character in all of Tolkien. Conceited, pompous, arrogant (yes, he deserves synonyms), stubborn, self-indulgent, gratuitiously violent, refuses to listen to any counsel but his own, and is responsible for the fall of Nargothrond. So he killed a dragon. Big whoop-de-doo. This guy's a loser. Does anyone in all of Tolkien feel sorry for themselves half as much? You can say Fëanor, but he never made up uber-emo pseudonyms for himself. Blech! Somebody slap this guy.
