I liked the second one... because smaug... But I did find the whole "nothing we can do, we're too late" bullshit ok... Give me the damn key and I'll run it along the wall until I find the hole.
The exact reason I disliked the second was because Smaug. That whole chase scene that dragged for 20 minutes wasn't even in the books. Should have put the time to better use, like Mirkwood. Can't wait to see this one tomorrow.
