The writers used to write original content loosely based off the comics. You're telling me that they're now just blatantly lifting from the comics? Then you're telling me you don't understand how the writers are running out of ideas?
I haven't read the comics, because like I said: I don't like the zombie survival genre. It's one of the most brainless genres out there (no pun intended). There's always zombies popping up for no explainable reason. Why are there zombies? Virus. Where did it come from? Someone either created it as an experiment or it fell from space. Is it stoppable? No, we're all doomed. What do we do? Camp out until we are overrun and some of us die, then rinse/repeat. Oh no, one of my family has turned! So drama.
And do you honestly not know of any other zombie survival media? We weren't talking about just TV shows, but the whole genre itself. Games, TV, movies, etc. Its getting ridiculous.
