...and one of the biggest flaes of this series is a lack of revulsion to the smell of a decomposing human. the longer it goes on, the more overpowering/sickening it gets. The governor should not be able to sit that close to his daughter, much like Michonne's two zombies should have turned her stomach.
It's hard to call that a flaw. It's zombie fiction. The realism of rotten flesh is just something you have to suspend disbelief on, like Star Trek & transporters
Frankly, Hershel's barn should have smelled like an open mass grave. It would permeate the whole farm. No one could live there with that... in reality. This show is no worse than any other zombie fiction in that respect.
