This is an excellent dark fantasy, an adult fantasy, if you will and the acting is well up to the story. It is a good tight script and keeps a fast pace. The allegory of a post nuclear age brought on by the advent of dragons freed from a millennial dormancy, points to the problems of survival in such a world. Many of our greatest science fiction authors have speculated on this, and this film tends to bring it all together nicely.
My one complaint with this film is that it was shot so dark that it is hard to see a lot of the action. The novel idea of one male for all of the female dragons is an excellent one however. Much of the look of the dragons tends to remind one of the 1997 version of Godzilla, with the lairs of creatures underground. Christian Bale was good as Quinn, and Matthew McConaughy shines as Van Zan. Gerard Butler was wasted in the film, not because his performance was bad, by no means, but because his character needed to have more to do. Still a very watchable film.
