Daybreakers is a superbly fresh and entertaining vampire experience. The film takes place in a dystopian future only a decade from now in which an outbreak in vampirism has turned the known world on its head. Contrary to the typical vampire film setup, vampires make up the majority of the world's population here and humans, who are either being framed for blood or are in hiding, make up only around 5%. In a way, the setup somewhat reminds me of the film Equilibrium, with vampires added into the mix.
The film finely balances sci-fi, horror, and action and I also really appreciated the utter desperation present in the film. So many action movies go so over-the-top in their action heroes that you never feel like their in any danger of being defeated, but here all odds are against our protagonists and, as events unfold, their situation grows gloomier and gloomier.
The entire cast--which includes Ethan Hawke, Sam Neill, William Dafoe, and Claudia Karvan—is on top of their game here and play the material straight, which is very refreshing. Especially Sam Neill, whom I've always been a fan of since I saw Jurassic Park as a kid, is great here and he really manages to steal the show in his scenes.
Also refreshing is the amount of bloodletting and thematic material present here. Make no mistake, Daybreakers is a "hard 'R'" and full of violence and grotesque sites like starving vampires turning into monstrosities that are hard to look at. The film also had ideas and much to say about a struggling society in the face of low supply to meet high demand.
I wasn't a huge fan of Undead, but the Spierig Brothers have truly crafted something special here. I do wish the film was a bit longer as I wanted to know more about the society the story took place in, but that's a testament to the film itself. If you're seeking a more adult vampire film with enough substance to excuse its style, I recommend Daybreakers.
