you shouldn't have to add that much more story into a post apocalyptic world with zombies in it... that's the point.. the survival adds enough to the show.
But when you start looking for sophie for a whole season, or introducing michonnes back story after 2 seasons of nothing, or bringing back the governor for one last hiccup in the story before you finally kill him, you begin to patronize the fans with a drama that moves extremely slowly and also shows the occasional zombie.
In other words....slow parts kind of like...Oh I don't know...Life.
Boring parts where they are held up in prison because they want the most of a normal life as they can get in a zombie infested world?
That is part of life. Wanting a community. Wanting a family. Wanting a safe life.
Life is not all action. Life has it's boring mundane times where all you want is a normal life even in an screwed up situation.
Now maybe they can add in a military take down of a nation with a plot twist of a guy being dead the whole time but not realizing it while at the same time having a non stop jason statham character who has to keep his heart beat above a certain number or die.
Of course that is not what is going to happen and that is hyperbole on my part but it illustrates a point.
They are going to search for a long time for a missing child...most groups of people that are like a family would.
Of course they are going to stay on a farm as long as they could...most people would.
Of course they are going to stay in the prison where they think it is safe...most people would.
But you are still complaining because it is extremely slow. Maybe you are better off going back and watching shows like Spartacus where the blood is always flowing because it is all action.
Maybe this show is just not for you and you are wasting your time watching it.
Maybe it is a show about trying to live when you are really dying and among the already dead.
