Post-apocolypse stories pretty much all follow the same pattern, survivors jockying for position in whatever hierarchy has developed, either with or without monsters/aliens/zombies. (Revolution is without, thank goodness.) The guys at the top are always the ones who have the guns, plus a seemingly inexhaustible supply of ammo. I did like Billy Burke's Uncle Miles; only he and Zak Orth (Aaron) seemed credible to me. None of the rest of the cast were strong enough to make their stereotypical characters into real individuals. On the whole, I agree with Austin; enough, already.
The first post-a stories came out during the cold war, and a lot of them featured a fanatical religious cult of some sort. They were either on top of the heap or a serious threat to those who were, but I guess people got tired of that for I haven't seen it for years.
