"I dont understand the science behind zombies.

Sure i can go along with the dead waking up eating others for sustenance.

But why don't they dry out? Why don't the characters move to the artic where the dead would freeze or the desert where they would dry out.

Why can't they out run them ? Why do they always twist their ankle while running away ?

The zombies at the very least should dry out and reanimate when it rains and surely due to evolution the only people left would have really robust ankles that don't easily sprain as they would be more likely to survive ?"

"R2-D2. This droid is like 50 years old by the time we get to the end of the Skywalker saga, and yet at no point has he become obsolete or incompatible with anything he runs into.
