That episode shows what an abortion the latter half of season three was.
Still, what a load of shit. Everyone just falling into line behind the Governor was far too convenient. Nobody bothered to talk to Hershel or Michonne to verify if what the Governor was saying was true or not. And Rick came across as being totally reasonable by offering to share the prison, which they proceeded to blow the f**k out of anyway.
All they did with the Governor this season was flesh him out a little and then they had another crack at the season three finale.
