I watched the first episode and cried and felt wonderful when it was over. I believe that is the definition of a "feel-good" story. I watched the second one and now I want to take some time and think about what I've seen and how great the performances are and I want to call my adult daughters and tell them about it and have them watch so we can fan-girl about it.
I want to curl up on a cozy couch with a fluffy blanket and cup of tea and box of tissues on a cold afternoon and watch the next episode.
It's unexpected, it doesn't follow the path you expect and best of all, it's a master class in subtle, nuanced acting.
