Sorry but the second season is truly garbage, one of the worst mafia shows ever made. The Calabrian twins are cheap imposters who speak with a horrible accent. The Cosoleto family is slightly better but still a lot of bad acting there. Not to mention that the story is completely ridiculous, they made the Ndrangheta look like a bunch of clown, while they are currently the strongest mafia group in Canada. In season 1 at least the Rizzutos are portrayed as powerful mafiosos, the Cosoletos act nothing like the real-life mafia.
By the way, are they supposed to be the real-life Siderno group? And the Langanas are like Commisso 'ndrina?
