Has The Hobbit Trilogy Deviated Too Much From The Book?

I do think that the films have deviated too far from the source material but that is not necessarily a bad thing. Adding in more detail and fleshing out Middle-earth a great deal more will hardly hinder the trilogy. It is a fair criticism to say it has added too much in, but the film industry is a business and if they can make three films that all gross around a billion dollars then they will surely take the opportunity.
