I love the zombie genre, but from what I've seen, many miss the point. They go for a more dramatic-tragic style, which isn't bad, but many quickly become boring and repetitive, like The Walking Dead from the third season onward. Others try to focus more on the human drama, and that's not bad either, but it's not a simple narrative and they often fall, again, into something repetitive and boring.
I think the best direction is something more like Z-Nation, with action, tension, and horror rather than a dramatic and sentimental approach.
