The major criticism of Justified’s third season is that it’s included a few too many plot elements. Especially in its latter half, season three has been a nonstop cavalcade of conniving and double crossing, and as such has, at times, been too busy to truly resonate. This was especially the case in last week’s episode, which moved neatly from one plot point to another, wrapping up the story of the Bennett money. However, this week’s finale, “Slaughterhouse,” is the sort of episode that can prompt a reexamination of an entire season’s worth of themes and ideas. I’ve long suspected that Justified has been illustrating a point about the ultimate emptiness of its characters’ continual struggle against each other, but it’s also a dark and unsettling examination of our relationship with the past.
