I really wanted to enjoy the 3 films, and to honestly believe that there could realistically be 3 films, and I suppose I did at least do the former... just. What I found most disappointing was that almost all of the additions to spin it out another 2.5 hours were all so lame. I could just about tolerate Tauriel, and I did actually quite like
Radagast, but I really hated the
Dol Guldur scenes from both the second and third films (except for when Elrond arrived-he's still cool). There was just no need, and it makes the Nazgul look so different to in LotR. Also, what was with Thorin running off like that with Dwalin, Kili and Fili at the end? Their leader had gone into hiding, so get back to the battle and make yourself visible! And what was Dwalin doing when Thorin was in trouble? Azog was meant to be dead by this stage, right (didn't Dain kill him at the battle outside Moria?). Remove Bolg and replace every Azog with the name Bolg and you have the villain of the book. No need for Alfred, or really much from Bard's famiily, Cut all that and you have 2 films. Also if Thorin had kept to the book and fought with everyone else, you'd have given Beorn and the Eagles a decent showing. Apart from the way the book just said essentially "Kili and Fili died-oh well" everything the book did was better (in my opinion).
On the subject of Dain, though, he was my absolute favourite character. Whoever decided that all dwarves should be grumpy Scotsmen absolutely made the entire series for me. Something about the line "Do you hear that, lads? We're on!" when totally outnumbered against Elves and Men was just brilliant to the extent that headbutting orcs wearing helmets whilst not wearing one yourself just seemed in keeping with Dain's gung-ho attitude and obvious sense of invincibility. Plus he rides a pig into battle-absolute hero (though it is not as cool as
Hobbit Farmer foil's pig). And I've never even liked Billy Connolly. Thranduil was good, too. Very elven and I'm still not sure if I like him or not.
Legolas on the stones was there for the 3D, and I hope will be removed from the DVD, but that is unlikely. For unrealistic special effects, I prefer Bombur in the barrel scene. The first 2 films were at least aimed at the younger audience, just like the book, so I don't think it was out of place.
One more thing: where was the cool score in the second and third films? LotR had some great tunes, and the dwarven theme from the first was quite catchy, too. Why was it never replayed (or even replaced) in the other films? That must be my biggest gripe with number 2, which otherwise was my favourite of the three.
