Season 1 and 4 are my favourite one. Joe's performance was amazing . Also the character Rhys Montrose is worth mentioning. But I really felt bad for Eddie and Nadia. Also Joe's unnecessary obsession with Marlene.....even their was no chemistry. Well.... looking forward to watch the final season. I really hope that Joe should be punished because there is too much blood in his hands.
P.S I love Joe's narrative...it's almost poetic ....you just can't help but rooting for him, though this is morally incorrect.
