AVClub: Is the Rayburn bloodline too poisoned to ever recover? By the end of “Part 19,” Kevin has decided he can’t be a father. In his mind, his family is fucked up, and it’s destined to be fucked up forever. The episode firmly roots itself in the show’s central themes, providing a narrative with very clear and stirring emotions. Bloodline could still use more mystery, more momentum to keep it from feeling like it’s stuck in the muck of mere aftermath, but “Part 19” is a superbly tense and anxiety-ridden episode that even offers a little bit of payoff. Much like “Part 17,” it tells a very cogent emotional story for each of its characters, with John’s ongoing arc sort of at the center of it all.
