Which good guy (girl) do you least like?

Okay I admit I'm not very far in reading the Lord of the Rings books at all so I can't particularly judge by the books. But in the movies the one person who really drives me up the wall is Eowyn. The way she took quite a fancy to Aragorn knowing he belonged to someone else just made my opinion of her go south. Plus she just rubs me the wrong way she seems so...I don't know...she just frustrates me to no end!
