Or it could also mean that this show doesn't provide the instant gratification that our society has come to take for granted and demand in everything we do. Cell phones, IMs, blogs, fast food, etc...
Like I have said several times already, this show is never going to be like that. The books are not, so why would the show? It is a show with a slow burn. The main focus of the show is continually building the characters and plots and interspersed are the zombie encounters. It is an ever present threat even if we don't actually see them (zombies) on screen for an episode or two.
I can see where you are coming from when you say the last episode was slow. I can even agree with it to a point. But to say there was little meaningful development is simply not accurate. Rick's character development has taken on a whole new direction with his shooting of the two scumbags in the bar. I imagine this will continue to play out over the rest of the episodes this season.
