My favorite Walking Dead wtf moment was them having a very hard time killing the zombies in full riot gear at the prison to then never think of using any of the armor for themselves.
Technically there was a scene or two when someone used the armor, which makes it worse because it was on their radar to use but instead they chose not to.
They always needed a short spinoff of a community in Montana or TX or the Amish that just lock down a full community in a few weeks, systematically destroys zombies, then goes on with life like it's no biggie. None of the terrible walking backwards oh shit moments that the show started to rely on. Just competent people handle things.
Such a shitty show after, as noted, the decent first season. Almost makes me want to do a rewatch just to laugh at it.
