You guys need to check out McMafia. It's a new AMC show. Only 3 episodes out, I think 4 airs tonight. I watch on demand so not really sure what night.
It's about a family of Russians ex mobsters exiled from Russia by the mafia and they now live in London. The children are basically western, having gone to boarding schools, and the son runs a hedge fund in London. It's about how he starts to get sucked into the old family business. But what's really awesome about it is the show is about the dirty finances behind the mob, not just the up front violence and activities. One of the quotes highlighted in ads for the show is a mobster saying these wars are won by lawyers in board rooms. It's called McMafia because the boss guy is trying to build his gangster business like you would a Mcdonald's franchise, but being everywhere. It's well acted and just a different show than most of the stuff on tv right now.
