Most zombie movies today have fallen back on humor, usually dark, usually lame. They’re neither scary nor funny. So it’s good to see one come along that just runs with it, and uses a sharp script to get the laughs. It’s downright infectious! Jesse Eisenberg plays a nerdy pandemic survivor who has remained healthy by following his own strict set of rules, which he will explain to you. He teams up with Woody Harrelson, a redneck zombie-slayer, and with Emma Stone and Abigail Breslin, a pair of uninfected sisters not nearly as defenseless as they seem. Bill Murray, in a cameo, has the movie’s absolute best line.
