I really just hate how zombies are a genre.
That's fine, but the fact is there has never been anything like this before on TV. And yeah, the zombie thing can be worn thin but thats why the drama thing makes up for it. In a film you have your standard 2 hour arc of trying to figure out what the hell they are and trying to survive etc. Okay, so lets say that's an episode or two of the show. Where do you go from there? Anywhere. The zombie apocalypse is just a backdrop for a story about these characters trying to survive.
I mean, if you are convincing yourself that you don't want to watch this show, that's fine too. But I would put some faith in AMC and Frank Darabont that they're going to make some compelling TV. I've seen the pilot, I thought it was great and I can't believe they're putting it on TV. Maybe the reason this got a greenlight was because they thought there might be an audience for zombie movies/shows out there but that doesn't diminish the quality of the show. Let Me In got greenlit because it was about vampires in this awful Twilight/TrueBlood era, but that doesn't make the film worse for it because it found a writer director who really connected with the material.
Darabont says "What’s innovative about this series is the extended and serialized human drama that’s going on. It’s not so much about the zombies, it’s about the characters - this group of human beings who are trying to survive, and come to terms with what’s happened and with one another."
