As one who adores the JRR Tolkien book, this has been a disappointing movie trilogy. Thankfully, The Hobbit: The Battle of the Five Armies is the most engaging of the three movies. Peter Jackson is in genius territory when it comes to detailing large scale fight scenes, body language and fighting styles of each race/army. Creative liberties, character quelling and additional characters are ho-hum. The only welcome deviation (spoiler alert-spoiler alert-spoiler alert) is the grand manner in which Smaug is shot down.
There are many aspects that the film scores on, not as ravishingly as the The Lord of the Rings trilogy. But as a Middle-earth expert there is a limit to the bad Peter Jackson can do. The Hobbit: The Battle of the Five Armies is still a monumental achievement, even if mitigated.
