"But I don't remember any spousal abuse in it, really..."
You had to be watching very carefully to see it. If you were watching Bobby you would have missed the moment.
If I remember correctly, it was the couple that was smoking marijuana. I think their scene had all those kids toys on the floor (excellent touch IMO).
There was a moment where the husband jerked his hand and the wife flinched. It wasn't out and out spousal abuse, but it was a moment that sowed the seed into the mind of the audience of "What is going on between these two?" It was one of the most brilliant, understated, subtle, loaded with subtext moments I've ever seen in theater. And that is why the Roundabout's production sucked big time.
If anyone ever tells you that you put too much Parmesan cheese on your pasta, stop talking to them. You don't need that kind of negativity in your life.
