Buying this DVD was worth it for the extras (besides, I got it for less than five bucks). The movie itself was alright. As one might expect from Peter Jackson, the effects are great. The story moves along but it is not terribly deep, it’s riddled with clichés and there’s some truly questionable acting (especially from Jack Black). But, again, the bonus features are very interesting and go into great detail about the technology and processes behind the film.
