Cooties

In this darkly comedic horror film, a mysterious virus hits an isolated elementary school, transforming the kids into a feral swarm of mass savages. An unlikely hero must lead a motley band of teachers in the fight for their lives against the hordes of infected children. The film's cast, including Elijah Wood and Rainn Wilson, delivers solid performances amidst the chaos, but it's the children who become the true antagonists in this R-rated thrill ride.
