This show is so good! First of all, the acting is really great. I'm in love with Lily Tomlin and Sam Waterston. Also, it's written really well. The characters are complex, there's good character development, and the writers know how to make their actors shine. There's so much heart and comedy in this show and it often makes me cry and laugh out loud. It's also opened my eyes to a lot of issues that older folks are dealing with.
