very low-quality writing and logic.
Most of the show makes no sense and motivations of various characters make no sense.
It this actually happened, EVERYONE would be armed to the teeth and shooting everything that moved.
No one would care about anything the government had to say if people were randomly being killed in the streets by the thousands by "vampire Things" unless the government was calling in the army to exterminate them all.
seriously, would you care about any sob stories if your kid or you were likely to be eaten on your way to school or supermarket?
