Cons:
- The uneven tone, I understand that the book is more of a children's book than the ring series. But the Hobbit film would have cutesy and cartoonish feeling things, closely mixed with some harder and more menacing things. With the Ring movies there was a more harder tone that was quite well held throughout, a lot of this was due to good vetting of the book contents, always the main challenge when doing a film version of a book.
- Making "enemies" such as the Goblin King and the Trolls into comedy characters. When these guys are in close up and their faces are highly articulate and cartoonish and they have their comedic dialogue, what this does is it removes the menace that these characters should have. What I mean is: think of LOTR fellowship and the Nazgul gathering at (what they think is) the Hobbit's beds to mercilessly slaughter them, no faces, no banter, just a slow menacing stride and intent = menace
- The Goblin town escape, again too cartoonish. Swinging rope platforms, and the final surfing/sliding down a huge slope. None of which felt real.
