YMMV / Daybreakers

  • Ass Pull:
    • While it makes sense how sunlight and water could act as some sort of defibrillator, no explanation is ever given for why blood from resurrected vampires will cure vampires.
    • It's possible that The Virus was mutated by the accident, not eliminated by it. Viruses have been known to absorb one another's DNA, so if the live, unmutated virus came into contact with the mutated virus, instant cure.
    • The fact that it does seem so unlikely might at least account for why Elvis had never thought to try passing the cure along via his own blood prior to finding out accidentally with Frankie.
    • While the sunlight and water starts their hearts, the Vampires react quite violently before becoming fully human - maybe their hearts starting kickstarts their immune system to fight off the infection, meaning anyone then drinking their blood also gets a dose of the antibodies that fight off vampirism.
  • Broken Aesop: The film set in a world of vampires and a dwindling supply of blood is basically one long analogy for our dependance of oil. Which is fine right up until the end where they create a substitute for blood which gives us not, "don't blindly waste resources and deal with the problem before it becomes a problem" but "blindly waste resources and science will stop the collapse of civilization just in the nick of time."
    • It gets further broken when you consider that alternatives to fossil-fuels already exist; they're just not yet economical.
  • Crosses the Line Twice: The blood substitute test. After the volunteer has a bad reaction but recovers, he merely says, "Ow." He then promptly explodes into bloody chunks, covering everyone with gore. It's horrifying and hilarious at the same time.
  • Narm:
    • The start of Bromley's death is horrific, what with the mass feeding and muffled screams - then a soldier rips off his head and just holds it in front of the camera as the eyes roll upwards. For some reason.
    • When the vampires who rushed and ate Charlie turn human, they are in turn rushed and devoured by further vampires in a slo-mo orgy of blood and violence. And then the last three surviving soldiers also turn human. If Christopher hadn't charged in just then and killed them all, who knows how long the chain reaction would have gone on?
  • Squick:
    • At one point someone is clearly showing drinking coffee, with milk... and blood.
    • Not to mention how horribly wrong a small argument over how much blood was in the coffee went...
    • The coffee shop's blood bags are marked by type, suggesting their customers were actually offered a choice of flavors when supplies were still plentiful.
  • What Do You Mean, It's Not Symbolic?: The hard way to cure vampirism is surviving sunlight by being fully submerged in water. In other words, a baptism.
