A few comments:
✓ In the '80s and '90s, three Manhattan filmmakers specialized in middlebrow, upper-middle-class entertainments: Mike Nichols, Nora Ephron, and Woody Allen. And I'm sorry to say that the best of them by far was Woody, b/c he was and is a monstrous sociopath. When Nichols and Ephron try to get dark, they make a somewhat downbeat, vaguely annoying movie like Heartburn. Meanwhile, Woody unleashes the torrent of bile that is Deconstructing Harry.
✓ There's a scene in this where Meryl Streep goes on the subway. I was shocked. It was absolutely unfathomable to me that Mike Nichols, Nora Ephron, and Meryl Streep could ever imagine going on a subway with the unwashed masses. Well... turns out it was a set-up for Meryl to meet a mugger. (The mugger, incidentally, is played by a young Kevin Spacey).
✓ This coasts along for a while on the charisma of Jack and Meryl.
