More was expected, more ought to have been delivered. 5/10 will probably watch again because I kinda have to when I re-watch the Middle-Earth Saga. Sigh.

Rating: 5/10 (15 December 2014)

(Extremely slight spoilers ahead)
It's hard to judge movies without regards to your expectations and the possible quality of said movie. Therefore I won't try. The Hobbit: The Battle of Five Armies is a climax stretched out far too long, walking in tonal limbo, with no discernible point.
The Lord of the Rings were movies suited to Peter Jackson's style of filmmaking, dramatic and epic both. I believe something similar could have been done with the Hobbit. However, it's as if Jackson (and the rest of the team involved, from actors to editors to writers) really aren't sure of what they want to do with the movies. It feels unpolished. The movie, for all the epicness it attempted, barely spans two days. It feels like a first draft. There was no reason to care about any characters. They gave you none. It's not enough to stick a character in the midst of an explosion; you need to care about that character. George Lucas once said that a visual effect, on it's own, is boring (oh my). Though the visuals of the Hobbit: TBOFA pleased me (colours, camera-work etc. and not the CGI), the enormous events/battles/falling stones are of little value.
I have read the book many times. I have also seen Lord of the Rings. The Hobbit: The book is an enjoyable piece of fiction, one that is best enjoyed near a fireplace, with hot chocolate in your spare hand. The Lord of the Rings is a series of movies where you are taken on a spectacular, moving adventure. The Hobbit: TBOFA is a movie I went to see because I felt I had to, and then went home to write a scathing review about.
I simply expected more from a filmmaker who has previously proved himself working with very workable scource material. More could have been done with a giant budget and good actors. Therefore I give the movie a 5.
