While directors Jonathan Milott and Cary Murnion want to have their laughs and horror, too, the film is something of a zombie itself: half-alive and bloody, but lacking any heart.
It's got an inspired setup, but then wastes it on a half-baked plot, a tepid sense of humor and a preoccupation with one-upping itself with its admittedly solid gore effects.
If you have always had the sneaky suspicion that children are little monsters, well, this movie is firmly on your side. It smartly blurs the line between pint-sized terror and flesh-eating hellion because really, who can tell sometimes?
