What he hell was Jackson thinking?

I don't get how the guy that made The Lord of the Rings trilogy made this mess.

War sheep plowing through armoured orcs. Dain repeatedly headbutting helmetted orcs. Why do the Orcs of the Misty Mountains appear better armed, armoured and organised than the Orcs of Mordor? Why does the film forget about the actual battle for an hour? Why does Azog use the least practical weapon imaginable in the final battle with Thorin.

Why is there a blind troll with prosthetic limbs? Why are the orcs so much least realistic than the ones in the 14 year older Fellowship? Why do the armies look so obviously like a CGI cutscene?

And what is with the utterly contrived love story?

Why does the relative size of the Hobbits, Dwarves and Orcs keep changing? Why is Galadriel so much more powerful than Saruman or Gandalf?

Why are there sled rabbits?

Seems to me Jackson caught the George Lucas Prequel Syndrome. Lets shove as much crap in as we can cos it'll look like, totally cool or whatever. To hell with logic and faithfulness.
