I’m with @JHS - I keep thinking the show will lose its appeal, but maybe the revolving door of characters keep it interesting and realistic.
I so enjoy the show’s pacing and gentleness. Love how the fashions and social topics are evolving, and appreciate that characters seem like real people - their flats look lived in and a little messy, moms are tired, not every character looks like a movie star.
IMO the show manages to present people of different ages, races, religions, opinions in a very respectful way.
