Another problem inherent to the zombie genre is that there are only so many situations characters can be placed in before it gets repetitive. Zombies are not interesting enemies; they shuffle around slowly and eat anything that comes their way. And apocalyptic scenarios limit the amount of potential storylines and environments for the characters to be involved in. Combine these two issues, and you have a recipe for repetition. There is a reason zombie films don't have this problem; films end before they get too boring. But The Walking Dead is a television show, and thus the story continues year after year, plodding along at a snails pace. Very rarely does anything interesting happen, and when it does, it usually involves either a zombie attack or a crazy person. Yes, according to The Walking Dead, everyone is either nice or a psycho. Every season of The Walking Dead has told the same story: Rick and the group try to survive, they get attacked by zombies periodically, and eventually some jerk ruins it all because, hey, why bother being a decent human being when the fate of the human race is on the line? In the case of seasons 3 and 4, they literally just reused the same villain; thats how repetitive it got. And that is only 4 seasons in. Imagine how repetitive it will be by season 6 or 7, which it will certainly reach considering how popular it is. Its not the shows fault; its the nature of the subject matter. Even the comic suffers from this problem. Unless the writers think of something completely wild, which risks alienating the audience, theyre stuck repeating themselves until the audience realizes this and gets bored.
