“Underworld: Blood Wars” (** out of four) was a visually dazzling but empty fifth entry in the now-wearisome series about the continuing adventures of vampire slayer Selene (Kate Beckinsale) and her battle to end the eternal war between the Lycans and the vampire clan who betrayed her in the past. Strictly by-the-numbers movie is hard to tell from previous entries and is for diehard fans of the series only. Even Beckinsale looks like she’s just going through the motions. Full of striking blue lighting and sumptuous cinematography that has become the series trademark but the story and characters could have used an infusion of fresh blood.
