For those of you who are just now discovering the HBO series My Brilliant Friend, I can say that you are in for a real treat. I've watched all three seasons to date; the fourth season has been announced and production is underway, with new actresses to play the parts of Elena and Lila. I'm very much looking forward to the new season. The series is directed by Saverio Costanzo, Alice Rohrwacher, and Daniele Luchetti. And if you want to start with the books by Elena Ferrante on which the series is based, you can find them on Amazon and Barnes & Noble.
Here are two posts I wrote in 2019 and 2020 about the books and the series respectively; I'm posting them again today:
