Yeah I enjoyed the power instability in NYC, I think that it was realistic and shown to many people how most mob wars happen within families.

That's why I lost interest in the final arch. It was too unrealistic, even for the show's universe. For 7 season we were reminded (most of the times by Tony himself) how the Lupertazzis were larger ("they have like 100 soldiers over there...") and more powerful. Yet, these Jersey Boys were able to engage in a war with them.

I mean: the entire DiMeo family fit a normal-sized safe house...with Buddha Greco counting for 2 of course.
