The Battle of the Five Armies title is a great exaggeration of what an army entails. The movie is about more or less a skirmish with some rather imaginative weaponry. The plot goes sideways and after two three hours long previous films we get a two hours and a half mess that is half completely over the top battle scenes and the other half people talking out of their asses. It is pure chaos, where orcs are either mighty unbeatable beasts bred for war or cardboard armor wearing morons easily defeated by fishermen's wives and children, as the action demands. Things start to remind of Pirates of the Caribbean, and not only because it's the same actor doing kind of the same stuff.
There is even a prolonged ending with Bilbo Baggings returning to the Shire, almost as if wanting to undo the good idea in the Lord of the Rings movies in which they removed the boring book ending with Saruman taking refuge in the Shire, and that portrays hobbits as petty bureaucratic creatures, rather than kind and resilient and courageous as declared everywhere else in the films. If I enjoyed the first two movies and wanted to see how it will all end, the third was a ridiculous failure, trying to do too much with too little: making a country brawl look like an epic battle, keeping the lighter more children oriented tone while killing characters and trying to express deeper heroic emotions, trying to somehow raise on the same level three organized military groups and a bunch of fishermen and animals and tying up lose ends that were there only to make this a trilogy rather than a pair of decent movies.
It is now when all the jokes about the eagles made in good fun in the first two movies (and in Lord of the Rings as well) turn smirky, when the only logic to the plot and action seems to be the panic of production companies trying to achieve their financial goals rather than tell a good story. It is here where the disappointment that everyone talks about when referring to The Hobbit movies raises its ugly head and grows on the small mistakes of the previous two movies. So in order to enjoy the trilogy, one must somehow detach themselves from the ending and see it as an imperfect finish to an otherwise fun movie, maybe imagine their own.
