Season 4 - Brutal.....no spoilers
One thing I have enjoyed about Gomorrah is that NO ONE is safe and this show is brutal.
I also like how there are mess-ups and failures and how at times there is no pulling a rabbit out of a hat to save the day.
And the transformation of Genny from Season One to Four. The actor does such a good job. Sort of like Vincent D'Onofrio in Full Metal Jacket - from buffoon to sociopath (though Gomer Pyle was more of a psychopath and Genny is more of a strategist).
