Television drama, whether about zombies or being lost on an island or trapped under a dome or in a world where electricity is non-existent, typically boils down to this: How people behave under extreme circumstances. Everything else is a matter of strange curiosity, though flesh eating zombies offer a more interesting back-drop than, say, having to fix a flat tire, even if every scene foreshadowed some alternate use for the tire iron ;-) Most of the time, the punch line in these dramas pertains to the ‘surprising’ things that people do, which they have always had the capacity to do, were it not for a moral compass, the confines of society, and, perhaps, the risk of incarceration. When these things go away, so do the inhibitions that safeguard us.
We all know that these inhibitions are not concrete – given the daily murders, rapes, robberies, etc – but we may not fully realize the extent of our interdependence, or, perhaps, how we take it for granted. There is an old joke about an out of town businessman that hires a taxi at night to get to a destination in a rural area. The taxi driver speeds through two consecutive red lights, leaving the passenger with an unsettling feeling, but then the driver stops at a green light and looks to the left intently. The passenger asks "why did you run through the last two red lights and stop at this green light?". The driver responds "my brother takes this cross road to get home".
Thus, it is only through convention that we can rely on one another for our mutual safety and well being, and we should not mistake our safety or success as anything less than this interdependence that we have come to rely on so indifferently at times.
