Nicky is a useless piece of crap.
I don't know how scripted this show is, some have suggested that the whole show is, I don't know.
However...SPOLIERS...SPOILERS...SPOLIERS...SPOILERS...SPOLIERS...SPOILERS...SPOLIERS...SPOILERS...
He is not the oldest son, yet he tries to tell all his brothers how to live their lives, even when they offer him help, assistance and support. Bobby was the one who helped Nicky get his family back from Florida when his business failed and help get set up back in NY. He gave no thank you for that, only grief and beating up the car at the scrap yard.
His wife is no winner, but he treats her in a rude, disrespectful and extremely unkind way. The way he speaks to her, I can't believe she puts up with it. When they went to the car dealership, he made a comment about "could she walk any slower".
He cheats on her, no apology to her. If he doesn't want to be with her, then separate or divorce.
He is terrible in business and horribly jealous and envious of all of his brothers who are more successful than him, especially Bobby.
He threatens to pull his dad out of the rehab center, even though it is obvious that it is much better for him to be there and his dad WANTS to be there.
Lastly, the joint party for their kids. He ignores Christopher in his toast and Bobby lets this go. However, when Bobby also gives his son a car (which Nicky knew he was going to do in advance), Nicky starts a fight in front of the whole family. He is the one who ruined his son's party by making a scene. His son didn't care that his cousin also got a car, he was still so excited that he just got an awesome Cadillac. It was Nicky who cared, not Justin. Nicky is insecure, annoying and childish. His voice is grating.
HE IS A DISGRACE.
