There’s a fascinating idea at the heart of Daybreakers, where a vampire plague has swept the world and everyone’s now a bloodsucker, but it doesn’t quite make for a fascinating film.
At its strongest when discussing the implications of that flipped population — light-secured houses, the few remaining humans farmed for blood — but weakest when it deals with plot, this sees Ethan Hawke’s compassionate vampire researcher flailing as he tries to develop a new food source for vampires threatened with starvation. A possible cure for vampirism appears instead, but with a fumbled last act and blatant appeal for a sequel, this finishes not with a bang but a whimper.
