I think the idea is that your are nervous for him. Could be hit at anytime (like always), could go to jail (they said an indictment was near).
The end was just the end of another day with any of number possibilities for the future. I thought the ending was super suspenseful myself but surprised there was no resolution as to what if anything happens to him. Maybe the idea is that nothing does.
Still, the set up of the scene was deliberate. If it was just the family together, no need to keep showing Meadow delayed and rushing in late. So the tension was real, a trick, or it is up to us to decide.
In a way I liked it, but then again - aren't the writers supposed to write the show? As opposed to my imagination.
If the black screen (and no music) meant Tony was dead, then all the stuff he went through in his Near Death Experience was just bunk, according to the producers, and there’s nothing. Pretty nihilistical.
