Bad Blood

A couple of evil twins are sent from Italy by the 'Ndrangheta to take matters in hand and soon start trying to muscle in on Declan's operation. But the mad Irishman isn't giving in without a fight.

Season 2 is action-packed, with a lot of edge-of-your seat scenarios. However, as well as being taut and with no unnecessary scenes or filler, it also manages to produce finely-drawn characters who you can actually care about. Let's hope they can keep the high standards for Season 3.
