Agreed. The crew is pretty slow in thinking. They learn very little. Emotions get you killed. They foolishly drop into one bad situation after another. Are they so shallow to not be happy to be alive at all? And having a crisis of conscience? I am to the point of rooting for the bad guys in some cases just to thin out the stupidity.
But how many man-vs-zombie battles can you have? How many man-vs-man battles can you have? Why don't they just find a safe spot, build up their defenses, and start rebuilding the world?
Simple. Because that would get boring and people would stop watching.
So every week it's the same thing: someone goes out on a "supply run," they run into an ambush, get trapped or captured, and then a group has to run out to rescue them. Sometimes the rescuers get captured too and then some miracle has to occur to free them all. Or sometimes the capture becomes extended and becomes the basis for a whole season's worth of drivel.
And one of these upcoming episodes, by some bizarre deus ex machina, Negan's captives will be freed, he will be killed (in a most satisfying way), and the show will plod on.
