Time Out says
The world is being overrun by vampires that look like giant living boogers with teeth. And only one man, the titular ass-kicking cleric (Bettany), can pick the snot. Director Scott Charles Stewart---reuniting with his growly lead performer after their John Carpenter--lite apocalypse thriller, Legion---gives this martial-arts-East--meets--wild-wild-West mishmash a sick-slick polish. (The dominant palette is blue-green on black for night, bleached-out monochrome for day.) And the film's save-the-niece-from-the-evil-others narrative is a blatantly direct steal from John Ford's The Searchers---without, of course, any of that classic's insights or complexity. But as solemnly noted during the sequel-ready climax, "This is just the beginning!" The God of Aborted Franchises will be pleased.
