Sure, of course. I just didn't know it was ever backed off of in that period.
I actually think much of S2's first and last halves are much stronger than some of mid-S3 where it flags for a little while, but that's me.
I've talked about it before, but Abby is the perfect encapsulation of why the show's transformation worked so well IMO. Like all the other women and families, you knew exactly where Abby came from because you saw it onscreen the day she drove into the neighborhood. You knew what she'd been through and what she wanted, and she didn't get it all immediately in S2 or S3. So you could root for her and make the adjustment (as with the other characters) when they dive headfirst into the '80s and much of the ensemble become career power players. Because they built the changes in themselves from the ground up, Abby most of all. That didn't happen with any of the other examples you cited, and doesn't happen with most daytime or primetime soaps today.
