On the one hand they really don't look like dwarves as Tolkien described them. I remember them tucking their beards in their belts.
On the other hand if they all looked as Tolkien described them they would all look almost exactly alike, and that would make for a boring-ass movie (not a boring ass-movie, more like a hairy ass-movie...but I digress). So in the end I have to say I really like the looks of the dwarves as revealed so far. I'm a pretty huge Tolkein fan (I try to reread the books every few years) and I completely understand the need to diverge from canon in order to adapt the stories to film.
