Daybreakers is an interesting movie. There are a lot of vampire stories where some powerful vampire wants to enslave the human race and keep them as cattle. But in those stories, the vampire is always stopped before they can actually enact their plan. Daybreakers imagines the logistics involved with 95% of humanity being vampires.
You can tell the filmmakers spent a lot of time thinking about how life would be different if everyone was a vampire. If everyone on the planet would die if they saw sunlight, how would cars change? How would houses change? How would cities change? Suddenly subways become the dominant form of travel. Also, there wouldn't be enough blood to go around and now you have a food shortage.
The movie has a great cast with Ethan Hawke, Willem Dafoe, and Sam Neill. While the setting and world-building is fantastic, I think the story's plot gets a little 'deus ex machina' where the solution was a little too easy just as a way to end the movie.
Anyway, here's a trailer. You can watch it on Roku, Pluto, and Plex. I recommend it.
I believe it was supposed to be the first of a trilogy or something.
Anyway, love the bit where the human talks to the vampire and the vamp turns around and the human disappears. Instead of the other way around.
