I think it is sad this series is ending. The producers made a huge mistake when they decided to focus on the Molly character, take her from being the responsible one in the family to the nutcase, and honestly, Melissa McCarthy is better in very small doses. They should have kept the focus on the ensemble cast, left the story as two lonely people who found each other, and let life happen.
This was a genuinely funny show, ruined by the very people who should have protected the initial story focus. But, whatever, they ruined the show and now it is gone.
