Without a doubt, one of the finest series ever. Olyphant is remarkable, and so is Nick Searcy as Art. But the revelation to me was Walton Goggins, as Boyd Crowder. All 5 seasons have featured Boyd as the complicated friend/enemy/ally of Raylan Givens, and this last will be no exception, I understand. The brotherhood between these two is constantly evolving and constantly surprising. Unfortunately, I don't have cable where I am now, and I will be at the least behind in keeping up in this, the final season.
Those of you watching this series for the first time, prepare to be hooked. It's one of the very best, and I don't know what I'll do when it's gone. Like the song says, "You'll never leave Harlan alive." And you might not want to leave at all.
