13 greatest horror movies of the last 13 years: '28 Days Later,' 'The Descent' and more
3. '28 Days Later'
Release date: 2003 (in the U.S.)
Scare factor (1-10): 9
Why it's great: There was a time when audiences associated zombies with those sluggish, slow-moving creeps in "Night of the Living Dead." Then came "28 Days Later." Danny Boyle's fast "zombies" aren't technically zombies, if you want to be picky about it (they're never actually dead or undead, just sick with a hellish virus), but their ability to move fast and rip people apart is a different and wholly compelling kind of scary. That the movie is darkly funny, smart and unafraid to take jabs at military power run amok just elevates the horror to art.
