I liked the movie quite a bit. It's vastly different from the book, but they're creating a more seamless story than exists in the abrupt change from the children's tale of The Hobbit to the significantly more adult Lord of the Rings. The changes didn't bother too much, even if the film does revolve around talking about the plot a lot. Unfortunately there's really no way around this, and once the audience is set up for the story (in this chapter), I suspect the other 2 movies will move along quite quickly.
Go back and watch Fellowship sometime - it's mostly people talking about the plot. Two Towers and Return of the King don't fall victim to this near as much. The same will be true of the Hobbit.
