Director Brad Anderson’s Blood is one of the rare vampire movies to focus entirely on the subject of drug addiction, which could make it a refreshing entry to the subgenre. Unfortunately, Blood’s script leans too heavily on tropes. Besides that, Anderson’s competent direction cannot help with Blood’s mixed messages about drug addiction and an ultimately unlikable protagonist.

Brad Anderson’s film steers a middle course between dysfunctional domestic drama and supernatural horror. That balance doesn’t completely work. But solid performances and some strong, occasionally unpleasant content make this an involving if not entirely satisfying watch.

It’s not high art or a great film, just a genre tale with a twist. And it’s a tad predictable, by the time that third act rolls around. But Monaghan and the kids sell the premise, and the movie plays.
