The movie centres around a conflicted vampire (Ethan Hawke) who wants to prevent the extinction of the human race not just to prevent vampire famine but on ethical and moral grounds. There are a number of other parties with other agendas like the corporate magnate wanting to corner a market (Sam Neill), the scientist who wants to see the benefits of his discovery and the soldier who is a better vampire than he was a human.
As a romp and a different slant on vampires (worth a look perhaps Zahir) it is OK but don't expect too much. It has been reviewed well in Australia, but then you could make something as awful as Jaws 4 here and they'd say it was great only because it was Australian (sorry Montresor ...but they would!).
The other thing about the movie is its allegory; you can't escape the oil and overfishing and even a bit of the Spice from Dune. But its played out as an observation and there doesn't seem to be a particular message that goes with the allegory; tho' I'm sure there are some here who will find one...!
If you see the DVD check out the additional material for a short film that's worth the five minutes to watch regardless of its ending
