Granted, this may be partly due to the fact that we are both hopeless LOTR/Hobbit/anything-related-to-Tolkien-including-The-Silmarillion fans.
But, come on. Who wouldn't be excited? Ok, there are a few. Book purists have expressed disappointment in some of the ways director Peter Jackson's expanded a relatively simple children's adventure into another three-film epic. Some of my friends, many of whom are even more intense fans of Tolkien's work than I am, point out flaws in the first film. Others bemoan the use of CG for the goblins and orcs, complaining that it takes away from the realism that imbued the LOTR trilogy.
Every film (or book, or comic-book, or TV show, or webserial...) has flaws and critics. I myself have some concerns about the "bloating" of this story. However, if a picture book like The Polar Express can be made into a successful full-length film, The Hobbit and all of Middle Earth's back story provide plenty of source material. The best choice anyone can make regarding these films is "wait and see."
(By the way, if you forgot which dwarf is which, refer to this helpful guide.)
Bilbo's tangle with the Mirkwood spiders looks satisfyingly frightening. According to one of the video diaries, Jackson is arachnophobic. I don't blame him. Considering how excellently Shelob came to life in ROTK, the glimpse we're given of Bilbo's task in the sneak peak sent chills up my spine. Ugh.
The last character I want to talk about is one that has not been featured in, well, anything. We know that Beorn (Mikael Persbrandt) is in the movie, thanks to a quick glimpse of him chatting with Gandalf in behind-the-scenes footage, but they're keeping a lot of details under wraps. I hope this is because they plan to blow us away with how awesome he is!
Ok, your turn! What are you most excited about? What makes you scratch your head? What are you worried about? And what's with the army of orcs that looks like it belongs at Orthanc?
