It's why I get miffed at all the dashing around in recent zombie films. It completely misses the point; transforms the threat to a straightforward physical danger from the zombies themselves, rather than our own inability to avoid them and these films are about us, not them. There's far more meat on the bones of the latter, far more juicy interpretation to get our teeth into. The first zombie is by comparison thin and one dimensional and ironically, it is down to all the exercise.
