I'm a pretty huge Tolkien purist, and I greatly enjoyed the last movie despite its inaccuracies. As an adaptation it suffers because it isn't really The Hobbit.
The Hobbit is a very light and very whimiscal fairytale. The first book I ever loved and an irreplacable treasure for me.
These films are much bigger in scope and intention. Parts of the book that were whimsical and silly were played entirely straight in the last film and it felt very odd. Still, it worked and it was a joy to spend a few more hours in Middle Earth. I bring on this next installment, even if I'm slightly skeptical of Tauriel and Legolas's presence.
