Now that I've seen the movies a billion times, the joy of watching them has devolved into pitiless mockery of the characters and actors I hate to love and love to hate. Here are the characters/performances I won't miss watching The Hobbit.
Aragorn
With time, Viggo Mortensen as Aragorn finally grew on me. Originally I hated his whiny, nasaly, annoying voice ("You cannot wield it!"), but the moment I always fall back in love with him? Return of the King: Elrond arrives at camp before the battle at Minas Tirith to present reforged blade, and Aragorn just WHIPS that sucker out. Like a boss. Nay! Like a king. He shouldn't skipped the song at his coronation though; Billy Boyd's Pippin is a hard act to follow.
Frodo
Elijah Wood is the worst fake giggler ever. But the scene that really kills me is when Shelob pokes him in the gut. There's a close up of Frodo frothing at the mouth, and all I can think about when I watch it is how much I want to punch him. Sorry, I've always hated Elijah Wood.
She's the most badly adapted character -- more of a hodge podge, really -- but Miranda Otto's Eowyn is comically bad for about 90% of her screen time. I will blame the extended editions for some of this, as a couple of the extra scenes are pointless besides adding to the incredibly awkward and (seriously, girl, duh) one-sided romance with Aragorn. Leave the love triangle to Twlight, and Eowyn can have her forced consolation romance with Faramir. (Had they ever even met?)
She's whiny, petulant, and -- and I know this is mean -- has the biggest forehead in the world, but she is awesome for four words in the whole trilogy: "I am no man." I just can't understand why someone with hair that long would braid it or throw it up into a pony before going to war. The best thing going for Eowyn is her foxy brother Eomer. I guess dirty horselords do it for me.
