Catastrophe (2015)

An unexpected pregnancy brings two adults into a relationship before they have had much time to work out how they will behave inside it. Sharon Horgan and Rob Delaney make verbal fluency useful for affection and spectacularly unhelpful in an argument. The four-series comedy offers a more sustained domestic companion to Fleabag's fear of being properly known. Its later difficulties ask more of the couple than simply maintaining a good line of banter.
