AVClub: The most obvious thing to say about Catastrophe is that it’s a skewed rom-com, taking the conventions of the genre — meet cute, surmountable obstacles in front of true love, happily ever after with marriage and children and the whole bit — and putting them in new contexts or lights. You’ve watched this show too, you get it. “Episode Five” once again dealt with rom-com conventions and this time it was gender roles involved in that whole happily ever after part. Women are caregivers, men are breadwinners. In this episode, both Sharon and Rob fight against this notion, succeed in bucking its conventions, but fail at bucking them as well.
