Gotta agree with previous comment - if you have read the book, do not watch the movie, or prepare yourself for a weak parody of the book. As a stand alone it is not THAT bad - certainly better than "Wizard of the Earthsea"... but not better than anything else of what I have seen from fantasy movies...except maybe some of TV series crap. Many of the ideas are brutally taken from other movies, and many of them - done poorly. A lightsaber alone in one of scenes was something... looked like they decided "oh gosh, those saber-things in Star Wars looks good, we need a bigger and better one!". The bat does look good...
Another failing, but this is usual one for most fantasy movies, there is a single example of partially functional armour in the movie - main heroine wears a mail shirt at one point. Rest wear some crazy mix of stupid looking non-functional stuff that would restrict movement and make it much harder to fight - no surprise that main hero ignores that crap and fights unarmoured, even if in book he preferred to wear a mail when possible.
All in all, it is clear that with enough money they can get effects on the level of world standard, but otherwise this movie is a waste of time.
