The final instalment of The Hobbit, starts with the spectacular sequence of Smaug burning down Laketown and his ultimate demise at the hand of the Bard. Unfortunately, this is also probably the only real highlight of the movie - a franchise that has strayed often too far from the story, and extended the plot line for no real reason.
The entire movie is about a battle - but much of it feels forced and over the top for no reason. As an example, it feels strange that suddenly the emergence of the 13 dwarves would immediately turn around the fortunes of the Dwarven and Eleven sides against the thousands of Orcs - a battle that was clearly being lost.
All in all, while being entertaining from an action movie perspective - the series has not risen to the heights of Lord of the Rings. It's sad - I think the Tolkien universe has a lot to offer - but not in this way.
