I think part of the problem with the 'fake looking' CGI people have mentioned is to do with framerates. Your normal CG_-heavy film runs at 24fps, which is the baseline framerate for all the computer animators to work to. Even then, that doesn't always happen. Anyone who's looked closely at Transformers: ROTF can tell that a lot of the CGI was animated at a sub-24 framerate. You only have to look at some of the Skids and Mudflaps scenes to witness the sort of jerky motion reminiscent of stop-motion era flicks. A common trick in such cases is to animate a CGI scene at a lesser framerate, then stick a load of motion blue on afterwards to try and paper the cracks. You tend to see this a lot in CGI-heavy films produced on a short schedule. Hence why the Transformers films, and many others, are such a mess of blurry, weird-looking CGI. With the Hobbit, the problem is made even worse by the fact that the stock footage is going at double the framerate, meaning the CGI also has to be animated at double the framerate. Motion capture can cover for some of this (which is no doubt why PJ was so insistent on using it for so many of the CG elements), but the majority of the CG work still has to be done by good old-fashioned key-frame animation. Doubling the framerate essentially doubles the workload, which essentially means you either need twice the animation staff, twice the production time, or you need to start using some serious shortcuts. A lot of the CG elements in The Hobbit seem to have that same blurry quality as stuff like Transformers, which I would assume is due to the CG staff trying to cover the fact that they simply couldn't animate all the CG elements at true 48fps, and therefore had to try and bluff a lot of it. Radagast's rabbits, for instance, look awful, as do the wargs. This then gets coupled with the usual CGI problems of having physics that aren't quite right, textures that don't look quite right, and that general sense of flatness and intangibility which is hard to get to shake, to result in CGI that just looks weird and not all that convincing. This is just my suspicions, and I thought I'd bring it up seeing as how many people seem to have mentioned the CGI as something that was frequently 'off' regarding the film.
