I watched "The Hobbit: An Unexpected Journey" yesterday night. It's no comparison to LotR, although it was quite entertaining, and thankfully far from a kids' movie (like the book translated into German that I read as a teenager and didn't appreciate at all). Frankly, I hardly remember the events of the book, so I'm not going to pick out all the scenes that weren't in Tolkien's work save maybe:

Radagast the Brown. Ouch. Peter Jackson, why, oh why, did you have to turn him into a gnarled wood gnome with something awfully similar to bird droppings adorning the right side of his face and the demeanor of a demented squirrel? Plus, the hare-pulled sled? Santa Claus on fucking acid, I swear.

Radagast was only mentioned in the books - once. No description, no details whatsoever. He used to be one the of the mysteries of Middle Earth, something deliberately left up to the reader to imagine. I always thought of him as a Saint Francis of Assisi-like character, tall, taciturn, ascetic, fiercely protective of his charges: all animals. And extremely powerful, although utterly uninterested in meddling in the affairs of humans, elves, and the like.
Also, there's this portrayal of Radagast in fanfic that I could very well picture, too.

In short, a competent, mysterious character, equal to the others of his order we, the readers, had already encountered: Gandalf the Grey and Saruman the White.

Not a comic relief.

Aside from that: I still can't tell the dwarves apart. Perhaps this cheat sheet might help?

Well, the three dwarves easiest to identify are the pretty ones: Thorin, Kili, and Fili.

What does it mean that I now want to read Thorin of Oakenshield slash, and can't think of a possible pairing that doesn't make me go all "bleh"? Perhaps Thorin/Legolas? There'd be enough strife in the background (what with Legolas being Thranduil's son) to make that pairing intriguing, but Legolas... urgh. He's just too Ken-doll like for me; always has been.

Blah.

Oh, wait, John H. Watson as Bilbo? Threw me violently during the whole movie!

Also, Gandalf (and later Elrond)'s arrogance was such a major turn-off in this movie, I'm glad The Hobbit was filmed after LotR instead of before, otherwise I would today have an entirely different opinion of both characters.
