I saw this in December - after waiting for it eagerly for the past two years+!
I absolutely loved it. I thought the dwarfs were all excellent (Thorin Oakenshield played by Richard Armitage was gorgeous - and very brooding) and I loved Aiden Turner and Dean O'Gorman (whom I have had the pleasure of meeting when I was in NZ a few years ago) as Kili and Fili.
Martin Freeman was wonderful as Bilbo and Cate Blanchett was as luminescent as ever as Galadriel. And it was wonderful to see the Shire (and Bag End) and Rivendell again. Elrond was much less serious this time around and in fact, the whole tone of the film was lighter (as it should be).
And the Eagles! I wonder if they ever get fed up of Gandalf using them as a Rescue/taxi Service???
I can't wait for the next one. I don't care if it's been filled out from the book, appendices etc. I just love the spectacle, the acting and the wonderful scenery.
