Alright, here's my two cents. I enjoyed the movie immensely. I thought it was very, very good. There will probably be spoilers in this post (mostly for those who haven't read the book), so read at your own risk.
I like that they 'fixed' the Black Arrow thing. I still wish it had been a NORMAL arrow like in the book, but I was glad that it ended up AT LEAST being shot by Bard's normal bow. I was a bit surprised that they didn't make Smaug's scenes longer, but I was pleased that they kept it simple.
It was interesting how they showed Thorin's progression of lust for the mountain's treasure, and also the reverse effect. I also must say that the three deaths in the movie were more painful on the big screen than in the book, and I'm glad I knew they were coming.
The Battle was of course amazing. People have complained about the amount of CG in the Hobbit movies, but I think it just makes them more.... not exactly whimsical, but less serious as opposed to LOTR, which is fitting of The Hobbit, since it is afterall based off a children's book. Also, for a great deal of the battle I was muttering/thinking, "Beorn and the eagles, we need Beorn and the eagles." AND FINALLY MY PLEA WAS HEARD AND THEY APPEARED, WITH NONE OTHER THAN RADAGAST. I WAS LAUGHING THEN.
I'm not gonna lie, I loved Galadriel giving Sauron what for (SHE HAD THE STARGLASS- THAT ONE SHE GIVES FRODO, FROM ELENDIL'S STAR, FROM THE SIMRAL, FROM THE LIGHT OF THE TWO TREES!).
I think my absolute favorite part was the end. The very end. Bilbo's goodbyes were bittersweet, but expected. What I was hoping dearly would be in the movie was where they try to auction off Bilbo's house when he comes back. I wasn't sure that it would be in the film as it was such a serious movie up till that point, and because such things were often left out of LOTR. I was delighted to see that that scene had made it into the movie- even Lobelia stealing the spoons! I was so happy.
All and all I am immensely pleased with this movie, all three of them! I also would like to put here, that I find it funny that I'm the girl who despises change of any kind, yet doesn't mind the changes in these movies NEARLY as much as some people. I have chosen to be happy with them; I am grateful that even if I missed LOTR when it was in theaters, I got to see the Hobbit in theaters. What happened with it, happened. I accept that, and I am content.
This last adventure into Middle Earth was bittersweet, but I will never find myself regretting it.
Mewsie out.
