The Rome mafia groups are not necessarily under the influence of the 'ndrangheta - they are quite a different breed, more urban, some of them are gypsies, like the Casamonica. Watch Suburra on Netflix, quite good and it's on the Casamonica/Fasciani/Di Silvio clans!
The Disney program is based on the Good Mothers, a (not so great) book by an English journalist about women of the mafia. Not holding my breathe. A good movie is Black Souls - Anime Nere (2014) on the 'ndrangheta. Very good.
I think Magliana neighborhood near the airport renowned for the Magliana Gang is still mobbed-up. Interested about them check Romanzo criminale.
Yes Black Souls is great, gritty and some real mobsters in it.
