I said in a review a couple of years ago of a series that was set in Algeria that there's a famous meme about Maghrebi women. It's a picture of four Arab or Berber biddies on a balcony looking in a different direction each with a statement that they are better than cameras. It's a notion that's been transplanted to the ghettos of Paris and the North African diaspora there - no one can do a thing in the "Cité" without everyone knowing about it.
There's another cultural reference here too that's true to life. Family trumps all, hence the English title. I live in Morocco and can attest to the truth of both of these concepts.
Putting family above all starts the chain of events that leads ever deeper into grim criminality, danger and despair. Twists in the plot lead to more and more extreme situations. None of it's believable, of course, but that's part of the charm of the series.
Just a mention of the "arguments" that others have criticised. Shouting and screeching is a normal means of communication between women of this culture. It doesn't even mean anyone is angry.
I loved this and despite having things to do, I binge watched till the end.
