Season 3 looks more consistent than S1 and S2. Episode 1 is not the only valuable one in whole season. The following episodes are pretty decent as well. Every detail about the choices that different figures made in such an end of world is impressive and worth to watch.
Evil is inexplicable. Baseness is woven into the fabric of life more tightly than goodness. Temptation, apathy, betrayal, deadening of thought and emotion, are part and parcel of the human existence, perhaps the very essence of it.
