This is my favorite episode of S6 so far. I liked all the story lines and pairings.
I've said this here in the past but as much as I've always loved Martin Sheen in just about everything he's ever done, he is completely lost in his scenes with Sam Waterston, which unfortunately, make up the bulk of his role as Robert. But put him in a scene with Lily Tomlin and the Sheen I've always loved returns. Past experience, I guess but they just seem so comfortable together. It's an absolute pleasure to watch. I think they bring out the best in each other. This is perhaps a UO, but I often think Lily's portrayal of Frankie is something of a caricature, but playing off Martin Sheen, she seems very real. JMO, of course.
I didn't care all that much for Nick in past seasons, but that character has definitely grown on me.
