Sometimes you gotta do dumb things to be the good guy. In the series so far, the Deputy goes into Atlanta thinking there's a safe zone there and looking for his Wife/Child. Well, what he doesn't know is Atlanta's been completely over-run by the dead and he finds out the hard way. Dumb? Not yet. So, lucky for him there happened to be a group of survivors, willing to help him, nearby in Atlanta when he got himself into trouble. The survivors were there to scavenge for supplies for their community camping outside the city. Dumb? Not yet, but pretty damn lucky. So, one of the survivors is a violent nut job racist who the Deputy ends up cuffing to a pipe on the roof of a building. It turns out all the noise the deputy made fighting zombies and getting rescued attracted a whole lot of zombie attention and the group of survivors is trapped inside a building the zombies are slowly busting into. In their haste to leave, they lose the key to the handcuffs and leave the guy on the roof. Dumb? Not yet. Pretty sensible if you ask me. Well, in previews for next week, the Deputy decides he needs to go back and rescue roof-guy. :|
Alright, now that might be dumb. But the Deputy has been consistent in character, in caring about people, even those already turned into zombies. He's got a powerful sense of right and wrong and of duty to the public. The writers set him up enough that going back to rescue roof guy in what amounts to a suicide mission is plausible, even if its more or less dumb.
I think the problem with a lot of dumb situations in horror film is laziness on the part of the writers. Here, in this series, they have first rate writers and directors and a network with proven high standards all of whom are going to insist on the highest quality story lines. So they can get their characters into and out of trouble without resorting to dumb or implausible short cuts. Shit happens every day to get people into trouble and its not always stupidity. Stubborness, pride, certainly, ignorance, of course - that makes the world go round - anger, resentment, jealousy and lets not forget duty, loyalty, training, and curiosity - it's not all bad, see. Humanity so flawed there's any number of reasons bad things happen and conflict develops. Resorting to developing the story's problem based on being dumb is lazy, pure and simple.
