A lot of people say that the series is not what it used to be (especially because there is not so much action as it used to be ). The way I see it, the director and the writers try to make the human decisions more realistic and to show how a human can evolve in a world like this. Yeah, everyone thinks there should be more killing, but this is not why the show has so much succes. I'm a zombie fan too and I think the series is going in the right direction without the zombie killing machines.
