"Unlike the tight little group of survivors in "28 Days Later," this one expands to the point where we don't much care about some of the characters (the blonde with the red lipstick, for example). But we do care about Kenneth (Ving Rhames), a gravel-voiced cop with hard-edged authority. We care about Michael (Jake Weber), a decent guy who tries to make the right decisions. And we care about Andre (Mekhi Phifer), whose wife Luda (Inna Korobkina) is great with child and will give birth at any moment; the way that plot plays out is touching and horrifying. We even work up some feeling for the guy marooned on the roof of the gun shop across the street, who communicates with Kenneth by holding up signs."
