Yes, I'm watching again. I had to see Nell one last time, and the early stories with Bucky and Pat and Jack/Mary, and some of the early moments of establishing the characters. The show did such a good job of using Frank to show us so many different people. As much as I liked some of Frank's later stories, after they finally got the right actor, I still wish they'd been allowed by ABC to kill him off.
I think Ilene Kristen is a real dynamo as she tries to find her feet in this role. There is a haunting quality to Delia which is lost by 1976 or so. It was there again with Randall Edwards, but again, the show didn't use it, because Delia is so tempting to just use as an instigator.
