My problem is that Danny was so central to the tension of every moment, so pivotal to the interplay between each character in every scene that I don't know what they do to fill that void. Danny is gone. The vicious cycle that started when Sarah died and the family all lied for their Dad over Danny is finished. Sure, we can witness the deconstruction of this family further... when someone inevitably ties them to the killing, to see Danny's son and the guilt that comes with having murdered the man he's looking for. And sure, we could see the family business collapse, Sarah come to terms that her family was an illusion all along and all of the kids one after another hauled off to prison in handcuffs.
But to me I'm just not sure the character drama works sans that category four hurricane that was Danny at the center of the action. Danny's son isn't going to be able to replace that. I'm sure they can still make some sort of family drama that might work, but I'm just not convinced the show is strong enough on its own to be particularly compelling without that fully loaded gun that made the entire drama feel like any moment it could go off and consume everyone. Danny was the main character as far as I was concerned, and John is no where near as compelling. Meg is OK, but Kenny is basically just bottled rage. He's not particularly interesting even in the first season.
I dunno. I think without Danny, it becomes a typical family drama that might barely work but is probably not going to be worth my future time. We'll see, I'll give it a fair shot but I think this feels like it could have been a one shot show.
