Things I don't like about The Hobbit:
They put Radaghast in there for some reason
They made Radaghast a drugged up kook
Freaking rabbits pulling a sleigh? What
They make Gandalf wimpy enough that he has to resort to poking the great goblin in the eye
They give the great goblin a tumor beard
The great goblin is supposed to have a really big head, not a really big tumor beard/belly
The stone giants aren't supposed to be mountain colossuses
They would have never survived being smashed into the mountain by the stone giants
They could have easily kept the troll encounter the same, but instead made gandalf randomly split a rock in half probably because PJ thought it'd be cool
They took a dead orc from the appendixes and made him a villian for no good reason
They changed the story of how thror was beheaded
They put Frodo in the beginning for no reason at all other than to reference the other trilogy
Saruman isn't supposed to be evil yet, he's "Saruman the Wise." He'd probably be wise enough to know that he should at least pretend to agree with the others and not be a jerk like he is in this movie
That meeting in rivendell with Saruman and Galadriel never happened
The dwarves look silly. They made Thorin and Gimli look good and dwarvish, why did they have to make the rest look like stupid Dr. Seuss characters?
Bombor was fat, but he wasn't so fat that he could barely move
They do some things thinking it's supposed to be a kids movie like the Hobbit was a kids book, but then they have things obviously not G-rated like slicing open Tumor-beard's belly and making Radaghast a drugged up kook
The eagles are supposed to come in later in a Warg encounter. Not when they're being chased by orcs as Thorin goes full-handicap trying to kill a behemoth orc with a stick
And I could probably go on
..dangit I hate when I kill threads
