How can corpses reanimate?
I mean, think about it, they died, usually for a reason. The body is broken to the point they died, usually in some catastrophic failure of major systems or a system.
How do they reanimate without any repair to the original damage?
I could accept that some corpses could become zombies IF the death was unusual like suffocation and didn’t result in massive trauma, but seriously, the whole concept is stupid from a medical/science standpoint.
What scientific rationale is there for it? Has anyone really tried to describe it? Once an animal dies, organs immediately start to decompose, individual cells rupture, and chemical breakdowns and processes begin. Think about the efforts medical science uses to do transplants and the short period of time a candidate organ has to be viable.
That has always been my problem with zombies—the whole idea is preposterous!
If you had watched the first season your question would've been answered. The writers did an very good job of explaining how the virus reanimates the zombie.
Yeah, I know. So unbelievable.
That is why science fiction movies that deviate from hard science are a waste. . .no matter how entertaining. . .like, those that have faster than light travel”—the whole idea is preposterous!”.
Just kidding. . .

There's all the explanation you need: "Somehow".
