A bunch of silly one-liners killing off the members of Thorin's Company one by one. I think I shouldn't watch the Hobbit when I am bored...
How the movie SHOULD have gone if it were more realistic:
One by one, the Company suffers casualties from a series of disasters.
...
Gloin's long beard catches fire over the troll spit, and he bursts into flames.
...
Bofur misses the cage at the end of the plummet into the Goblin Caverns.
...
Bilbo is dragged off the bridge by a Goblin, hits his head on the ground, and dies of a concussion.
...
Kili learns that swords do not block arrows and is killed by an arrow through the eye.
...
The "magical" boulder rolls in the wrong direction and squashes Dwalin.
...
Fili misses the jump to the swinging bridge in the Goblin Caverns and falls off the cliff.
...
Bifur dies of brain trauma after all the excitement, and it is confirmed that objects driven into the head are very deadly.
...
A piece of wood stabs through Nori's heart when the dead Goblin King lands on top of the bridge.
...
Oin does not catch a tree during the domino effect in the final Warg battle, and is eaten by Wargs.
...
Dori cannot "magically" catch Gandalf's staff, and both he and Ori plummet to the ground.
...
Thorin's face is bashed in by Azog's club and he dies instantly.
...
Balin, having already faced enough war trauma for his hair to go white early, dies of a heart attack after watching everyone else die.
...
Bombur injured his tailbone after crashing through the Elven bench, and stayed in Rivendell to recover - making himself the only Dwarf to survive the quest.
...
Gandalf is forever disgraced for leading the last of the line of Durin to their deaths.
...
All the fans are heartbroken and traumatized for life.
I suppose this is why the movie was less realistic than one would suppose...
