I have just discovered this and binge watched series 1 and 2. I'm delighted there is to be another series and hope her relationship with Michael doesn't go wrong. I just love the way he looks at her, such love.
I do find the constant interruptions, which means no one ever seems to get to the end of a conversation, annoying. That said I think it is wonderful comedy/pathos and spend time thinking about the back story to the characters.
My daughter laughs whenever the old couple are on, she says they are similar to me and the husband. Can't see it myself.
