Readers of J.R.R. Tolkien's book "The Hobbit" know that the author saved the best material for last, as Tolkien wove his story strands together to create a parable of the wages of vengeance and greed. It's this narrative balance that makes the last installment of Peter Jackson's movie trilogy, "The Hobbit: The Battle of the Five Armies," the best of the three "Hobbit" movies, moving from an enjoyable action/battle movie with fantastic visuals into the realm of authentic tragedy.
