In reply to Liam M:
> Epic pitched battles and big scale politics are what the LotR is about, but not The Hobbit.
This was very much my feeling, too. However:
> If he wanted to make a proper prequel to LotR, he should have taken on parts of the Silmarillion.
I'm very rusty on this, but I think that's pretty much what he has done.
Radagast, Sauron as the Necromancer of Dol Guldur, a mention of Ungoliant (though he seemed to try to associate the spiders with Sauron, which I think is wrong - they're an independent evil force, possibly even worse and not allied.)
It's interesting reading others' thoughts on this film. I expected to either love or hate it, rather than just enjoy it mildly!
