All credit to The Walking Dead for showing us the compound raid in this episode, and not stretching out the tense preparations for the full hour. This show has insane momentum this half-season, and they somehow managed to amp it up.
Yes, killing is bad! But sometimes it's good! That's the long and short of it, and no matter how many times The Walking Dead puts its characters in these situations, that will be the answer. And again, that was the answer this time.
