I re-read the book a couple weeks before movie released to refresh the details.
Great, great book.
Movie? Very slow. Start. Like..an hour. Seriously, an hour of the party in the Hobbit hole trying to convince Bilbo to go on the quest.
Much too long.
Also, Gandalf's brother(?)..Rhadagast is in this movie..not in original book.
The scenes in the goblin cave (toward the end) are worth the price of the ticket. As is the scene with Bilbo and Gollum when they're having the riddle contest.
This is bodybuilding related becase the Orc King astride a white warg is obviously not natural. He's stacking.
And one more thing: The scene in the Goblin cave, when Gandalf appears in a flash of light...was fucking awesome. That's how I imagined a fucking wizard would do shit.
