Rehearsed, real, I'm not sure. This one looked to be far more serious than any I'd seen before.
I don't think the two of them can work together. Sr., has had problems with drug and alcohol abuse in the past. I don't think he's all there on a social level. Business wise, I'd say he's got a good head on his shoulders. He's done very well.
Junior is one of those people for whom rules are meant to be broken. He's the most creative of the lot. He's key to the business, IMO. The two of them are going to butt heads until one or the other leaves this earth. They are both too much alike and not enough alike.
If you've seen the previews and some commercials, it's apparent they've reached some kind of agreement. It's not going to last, but this is the way they interact with each other.
These are my observations based on what they choose for us to see. Do any of my thoughts mesh with reality? Who knows?
Junior is a big contributor to the business, with Mike, you'd do better to throw money down a hole in the ground.
