Daywalkers and vampires are feuding, a camp brings their children together, a romance instructs the feud to end. If this were the first of its kind, it would be a thin camp movie with a fair instinct against inherited enemies. It is not the first. It is the fourth delivery of a policy the studio has decided is a genre.

Skip. If a younger child sees it anyway, the one usable line is the old one: do not make a child carry an adult's enemy. You can say that without the film.
