I loved it!!! I'm sad to know things took a bad turn for the best friends.
I loved Katherine's performance, but I am on a love-hate relationship with Sarah's. It seems to me the younger Kate was more likeable. The going through a divorced Kate - she's just messed up. Can't fully process what she's going through but she's going deep with Travis, only to take a step back and realize she still loves her ex. Maybe it doesn't help her character being played by the actress. Kate is such a sweet and gentle soul with a twist and deserved someone else portraying her. And for some reason, the 80's Tully seemed to suit Katherine while Sarah's Kate made her just look so old! I couldn't picture her being a charming young woman. It's just my take.
Despite the above mentioned, each episode kept me close to tears. I really felt what they were fling though - the good and the bad. I only hope the go for season two!
