Jackson was in a no-win situation
I don't like the Hobbit trilogy because they try to be too much like LOTR, and the Hobbit is a light-hearted children's story. It's ridiculous that because the studio wanted three LONG movies that were popular, they have to throw in Legolas, a love interest, Sauron, and lots of little bits from the LOTR appendices that really aren't needed, BUT the studio would never accept Hobbit movies that were entirely different in tone and structure. It's really a no-win situation for Peter Jackson, and I feel sorry for him.
