Yes, love it. I could watch Lily Tomlin in anything but the writing is so great. I really like the side story of the 2 guys working out a path in the gay community.
The thing I love about the show as a whole is it's depth and complexity of characters. They are real and fallible and not stereotypes. It seems that the 4 main characters (because I see the show, especially in this second season as Grace and Frankie and Robert and Saul) are navigating not just the divorce and creating a new life in the gay community, but so much of what life is like when you aren't 20 anymore.
For a "sitcom" there is a whole lot of real life.
