Anyone not able to see that the phone scene wasn't the end, but the just the beginning of Rick's breakdown doesn't understand how the story is told.
This right here.
It seems like most folks disliked a lot of season two because it was too "talky" and like the first half of season three because the show finally started plowing through the plotline.
I fall into that audience generally, but sometimes you need a "talky" transition episode to lead into the next coming shitstorm.
There has to be some kind of characterization and motivation for the shoot 'em up and zombie headstomping or else the show is nothing but zombie gore porn.
