The thing about the show that bothers me the most is the inconsistencies. In the first season, the survivors had to smear themselves in the blood of a zombie so that the zombies could not smell them. This season they could hide under cars and the zombies wouldn't smell them. Also in the last episode, they showed Rick eating a sandwich. I am not so sure there would be any bread that is still good anymore.
There are a thousand hacking at the branches of evil to one who is striking at the root.
