Daybreakers (2009)

A decade after the majority of the world's population is turned to vampirism their food stock (i.e. fresh human blood) is in short supply. If an alternative isn't found the society that until now has continued to function just fine will begin to die out, but not before the thirsty citizens turn on themselves.
Ethan Hawke stars as a haematologist searching for a viable solution. He's in the belly of the beast, but is there for the right reasons.
It's certainly an interesting spin on the vampire myth, with an always pertinent social message as undercurrent, but the film rarely manages to break out of its own muted atmosphere. Perhaps it was never meant to and I'm wrong to assume otherwise? Either way, in my mind its sombre mood successfully elucidates its message but also prevents it from being more memorable.
