I found myself not caring about anyone except Bilbo, and Tauriel after she stood up to Thranduil. I thought about it when Thorin's dwarves finally charged out to join the battle. That should have been a big lump in the throat moment like the Ride of Rohan in RotK. And there I was watching with no more emotion than if it were a football highlight.
The movie was a disappointment - not because it was horrible, but because it was so mediocre and failed to wrap up the trilogy. As much as we all make fun of the RotK endings (all of them!), they at least left you feeling that you'd really finished something. Here: Thorin's dead, bye Balin, gimme back my spoons Lobelia.
