The film earns a score of 62 out of 100. Set a decade following a catastrophic event that transformed most people into vampires, the story centers on a medical professional working to create an artificial blood source—an effort intended to safeguard humanity and also maintain sustenance for the vampire population. The performances were solid and the movie proved diverting, though it wasn’t without its shortcomings. I didn't feel completely drawn in by the narrative; it lacked a certain emotional impact. It seems improbable that a solution like this would have remained undiscovered after ten years had passed, and whether what they found could truly be considered a cure is questionable, given the immense consequences involved. The violent conclusion was enjoyable, however.
