I'll be a dissenter. I enjoyed it. A lot.
We saw it as a family yesterday. First time for DH and I, second time around for DS and DD. The kids enjoyed it as much as they did the first time.
I was once again awestruck by Tolkein's world-building and Jackson's ability to recreate it on film.
3D - I've never been a fan but I didn't mind it on this film. I've think I've only seen two other 3D movies, Avatar and the last Harry Potter film. I thought the technology has come a long way in just a couple of years.
It's been many years since I read The Hobbit and I haven't read the appendices to it, I've only read Book 1 and half of Book 2 of LOTR (repeatedly, I always get stuck about halfway through TTT) and I've never read The Silmarillion. I appreciated getting the Erebor backstory at the beginning of the film. It was necessary and useful for me. I don't think it would have worked as well to insert it as some kind of flashback later in the film. The kids have read everything much more recently than me (except The Silmarillion, it seems to be a gap in our family library) and they agree.
I liked the little touches that were incorporated without being headlined. DD pointed out that the youngest dwarf is the baby brother to two others. They often make little protective gestures like pulling him back out of harm during the chase scenes.
I liked the humour.
The chases and action scenes went on too long for my taste, but I feel that way about every single chase and action scene I've ever watched in any movie. I always think scenes with chases, fights and battles could be cut by a third or a half.
I didn't mind the appearance of the dwarves. Yes, some of them didn't look particularly dwarvish. There was a spectrum of dwarf features and I'm willing to accept that. It was hard enough telling them all apart (when I said that yesterday, DS said that's racist, btw).
Martin Freeman was excellent.
I am not a huge Cate Blanchett fan so I always have to fight my opinion whenever I watch her. I did leave the film thinking about how little women mattered to Tolkein. To me, it was very noticeable that there are no women in this world. Galadriel is so other-wordly and spiritual that I don't think she really counts.
It was good to see Christopher Lee again. Nice touch.
Andy Serkis is a genius. Smeagol/Gollum - just amazing.
I wondered whether Ian McKellen gets tired of yelling "RUN!" at regular intervals throughout these movies. It must happen about every 8.25 minutes and coincides with every action scene. Does he get an extra fee every time he shouts it? I think they could let one of the dwarves take that line once in awhile - maybe the baby brother dwarf.
The one element of the film that I disliked intensely was Radagast. His image, his language, his portrayal, everything about him, was just WRONG. He is the Jar-Jar Binks of the franchise.
I'm looking forward to the next installment.
