Over the course of the lengthy running time of An Unexpected Journey and The Desolation of Smaug we've spent a lot of time with the characters in The Hobbit's universe. But we can't help but feel as if we don't really know many of the characters we've met. Part of this problem can be seen as an extension of the previous point on this list - many of them seem to exist only to serve as vehicles for exposition, providing the audience with backstories and details to flesh out the plot. The problem with this lies in reducing them to mere narrators, devoid of any real personality of their own. This can't really be said of the majority of the dwarves, and in this respect their lack of character development is harder to dismiss as a product of exposition. Despite sharing an ample amount of screen time over the course of the movies, most of the dwarves feel like one dimensional extras with very little depth. Admittedly there are quite a few of them, but perhaps a script which injected more personality into each of them would have livened up their presence on the screen.
