Daybreakers is the rarest of Hollywood Action-Horror crossovers: it succeeds in both genres and has a concept that allows it to pursue complex moral questions and modern-day issues without ever getting preachy or lame. The script had flaws, but- and I very rarely say this- the rest of the film was good enough to overlook the script issues.
Vampire films are a dime a dozen these days. Two Twilight Saga films come out every year; rip offs of those, and even things like HBO’s True Blood crowd the marketplace for vampire-related fiction. In order to stand out, a vampire film has to be really different, with a special “hook” to grab you and interesting characters to make you stay. Daybreakers does this incredibly well. Here’s the hook: In the year 2019, most of the population has been transformed into immortal vampires. However, they require human blood to live. (Their own blood disfigures them and causes brain damage.) For the last ten years, human blood as a resource has been dwindling, causing a need to find a blood substitute.
The beauty of Daybreakers lies in its not-so-subtlety and beautiful use of blood and gore. It’s a great big-budget b-movie.
