It was Kili at first, he makes a great impression, but I think I have to go with Nori, because he's so shifty. Go criminal dwarves! Though, I think we can all agree that Radagast's rabbits stole the movie.
My favorite characters in the Hobbit are Fili & Kili because they're cute, Gandalf because he's so cool, Bilbo since he seems like a nice guy & he's also cute, & Thorin since he's pretty cool. Radagast was pretty funny and because he was played by the 7th Doctor, Sylvester McCoy.
