Pine Barrens is also the best rated episode on IMDB with 9,6

My favorite episode, Commendatori S2 E4, has 'only' a 8,7 but for me it's one of the best because of the visit to Naples and everything that went with it, like the scenes with Annalisa and the other Camorristi, plus the introduction of Furio Giunta of course. Also the scenes meanwhile in Jersey with Pussy, Jimmy Bones and the ball-peen hamer were very memorable..
