It's an exciting, well-directed thriller that, while providing more than enough action and gore to satisfy genre fans, also offers the political commentary that has characterized zombie movies.

There isn't much acting here, but there is entirely too much vomiting, and the prose turns laughably purple, too.

Even though I knew the scares were coming, I jumped out of my seat a few times.

[Director] Fresnadillo drives the scenes of zombie mayhem with a jumpy camera and a fractured editing style that adds a sense of panic to the chaos, as if seen through the terror-stricken perspective of an adrenaline-laced bystander.
