One of the writers is Sharon Horgan who wrote and starred in a brilliant sit/com called "Catastrophe", very funny albeit rude!.
Motherland is well observed, particularly the Queen Bee/bitch, sure there's one of those in every school. My first experience of "the muffia" when my first one went to school somehow seemed worse than my own school days. They were out in full force, what seemed like every day selling something or other from tressle tables in front of the main entrance, so the beta mothers such as myself had to run the gauntlet while we were pestered to buy tickets for dinner and dances etc. etc. My husband did the school run occasionally and when asked to buy a ticket for such an event he replied "I'll happily give you some money not to come" One of my friends at the time, a single mum, who didn't have spare cash did speak up and said she found it unacceptable to be hassled in this way just trying to deliver her child to school.
